## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of and claims priority to U.S. patent application Ser. No. 13/323,191 filed on Dec. 12, 2011, published as US 2013/0150605 A1 and entitled “Preparation of Transition Metal Carboxylates,” which is incorporated by reference herein in its entirety.


TECHNICAL FIELD OF THE INVENTION
This disclosure relates to transition metal carboxylates and methods for making transition metal carboxylates, including chromium-containing carboxylates useful for preparing olefin oligomerization catalysts.
BACKGROUND OF THE INVENTION
The trimerization of ethylene to produce 1-hexene constitutes a commercially significant process for the selective preparation of this alpha olefin, which in turn is useful for preparing a range of polyolefins, usually as a comonomer with ethylene. One widely employed catalyst system utilizes chromium carboxylates as a component. For example, tris(2-ethylhexanoate) chromium(III) compositions are utilized as a component of some effective chromium (III) catalyst system for the selective trimerization of ethylene to 1-hexene.
Batch-to-batch variations in the quality of commercial chromium(III) 2-ethylhexanoate, and the attendant inconsistency in catalytic system performance, have prompted the search for new synthetic approaches to chromium carboxylates. This search for alternative preparative approaches is further motivated by the desire to improve productivity and selectivity of a catalyst system and to attempt to reduce catalyst system cost. Therefore, there remains a need for new synthetic approaches to produce transition metal carboxylates.

DETAILED DESCRIPTION OF THE INVENTION
In one aspect, this disclosure provides for synthetic approaches to prepare transition metal carboxylate compositions, that is, compositions comprising at least one transition metal carboxylate compound. The term carboxylate is used herein to describe chemical moieties that contain one or more carboxylate functional group. For example, the Group 1 or Group 2 carboxylate starting materials and the transition metal carboxylate compositions of this disclosure can encompass carboxylate-containing moieties of the general formula (O2C)rR1c, where the carboxylate-containing moiety has r carboxylate groups and r can be an integer from 1 to 4. In this aspect, for example, the methods of this disclosure are applicable to the preparation of compositions comprising simple mono-carboxylates such as O2CR2c.
A common synthetic approach to prepare transition metal carboxylate compositions involves reacting a transition metal acetate precursor with the corresponding carboxylic acid, for example propanoic acid (CH3CH2CO2H), butyric acid (CH3CH2CH2CO2H), and the like. For example, commercial preparations of chromium (III) carboxylates such as Cr(2-ethylhexanoate)3 (“Cr(EH)3”) typically entail heating chromium (III) acetate in the presence of excess 2-ethylhexanoic acid. The resulting acetic acid, excess 2-ethylhexanoic acid, and water typically are removed to the extent possible by heating the reaction mixture under vacuum. Alternatively, the chromium(III) carboxylate has been produced by the reduction of chromium trioxide in the presence of the carboxylic acid where the reductant is the carboxylic acid. For example, commercial preparations of chromium(III) carboxylates such as Cr(2-ethylhexanoate)3 can entail heating a mixture comprising chromium trioxide and excess of 2-ethylhexanoic acid. However, these methods typically can leave residual carboxylic acid within the chromium(III) carboxylate compositions, introduce difficult to remove water into the chromium(III) carboxylate composition, and/or produce oligomeric chromium carboxylate compounds. Because some of the intended applications of the resulting Cr(EH)3 are water- and/or acid-sensitive, the presence of water and residual carboxylic acid can complicate the use of these compositions in some applications. Additionally, the presence protic carboxylic acids and chromium carboxylate oligomers can introduce problems in the production of olefin oligomerization catalyst systems and their subsequent use in oligomerizing olefins. For example, and not to be limited by theory, the protic carboxylic acids can consume cocatalyst and increase catalyst system costs while chromium carboxylate oligomers can lead to insoluble products which must be filtered and/or increase polymer production during olefin oligomerization. Accordingly, this disclosure provides synthetic methods, which reduce, minimize, or substantially eliminate undesirable protic sources, such as H2O and/or carboxylic acid such as 2-ethylhexanoic acid, and/or minimize the presence of chromium carboxylate oligomers. Specifically, this disclosure provides for an improved process for producing transition metal carboxylate compositions comprising contacting a transition metal precursor and a Group 1 or Group 2 metal C3-C25 carboxylate in a polar aprotic solvent to provide a mixture comprising a transition metal carboxylate.
To define more clearly the terms used herein, the following definitions are provided. Unless otherwise indicated, the following definitions are applicable to this disclosure. If a term is used in this disclosure but is not specifically defined herein, the definition from the IUPAC Compendium of Chemical Terminology, 2nd Ed (1997) can be applied, as long as that definition does not conflict with any other disclosure or definition applied herein, or render indefinite or non-enabled any claim to which that definition is applied. To the extent that any definition or usage provided by any document incorporated herein by reference conflicts with the definition or usage provided herein, the definition or usage provided herein controls.
Groups of elements of the table are indicated using the numbering scheme indicated in the version of the periodic table of elements published in Chemical and Engineering News, 63(5), 27, 1985. In some instances a group of elements can be indicated using a common name assigned to the group; for example alkali metals for Group 1 elements, alkaline earth metals for Group 2 elements, transition metals for Group 3-12 elements, and halogens for Group 17 elements.
Regarding claim transitional terms or phrases, the transitional term “comprising”, which is synonymous with “including,” “containing,” “having,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. The transitional phrase “consisting of” excludes any element, step, or ingredient not specified in the claim. The transitional phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristic(s) of the claimed invention. A “consisting essentially of” claim occupies a middle ground between closed claims that are written in a “consisting of” format and fully open claims that are drafted in a “comprising” format. Absent an indication to the contrary, when describing a compound or composition “consisting essentially of” is not to be construed as “comprising,” but is intended to describe the recited component that includes materials which do not significantly alter the composition or method to which the term is applied. For example, a feedstock consisting of a material A can include impurities typically present in a commercially produced or commercially available sample of the recited compound or composition. When a claim includes different features and/or feature classes (for example, a method step, feedstock features, and/or product features, among other possibilities), the transitional terms comprising, consisting essentially of, and consisting of apply only to the feature class which is utilized and it is possible to have different transitional terms or phrases utilized with different features within a claim. For example, a method can comprise several recited steps (and other non-recited steps) but utilize a catalyst system preparation consisting of specific or alternatively consist of specific steps and/or utilize a catalyst system comprising recited components and other non-recited components.
Within this disclosure, use of “comprising” or an equivalent expression contemplates the use of the phrase “consisting essentially of,” “consists essentially of,” or equivalent expressions as an alternative embodiments to the open-ended expression. Additionally, use of “comprising” or an equivalent expression or use of “consisting essentially of” in the specification contemplates the use of the phrase “consisting of,” “consists of,” or equivalent expression as an alternative to the open-ended expression or middle ground expression, respectively. For example, “comprising” should be understood to include “consisting essentially of,” and “consisting of” as alternative embodiments for the aspect, features, and/or elements presented in the specification unless specifically indicated otherwise.
The terms “a,” “an,” and “the” are intended, unless specifically indicated otherwise, to include plural alternatives (e.g., at least one). For instance, the disclosure of “a chromium halide hydrate” is meant to encompass one chromium halide hydrate, or mixtures or combinations of more than one chromium halide hydrate unless otherwise specified.
In this disclosure, the terms first, second, and third, among others, can be utilized to differentiate multiple occurrences of a similar element. For example a method can utilize two or more solvents in different steps of a method, or alternatively two different solvent in a mixture. The differentiating term can be applied to any element described herein when necessary to provide a differentiation. It should be understood that the numerical or alphabetical precedence of the differentiating terms do not imply a particular order or preference of the element in a method or compound described herein unless specifically specified otherwise.
In this disclosure, a process can have multiple steps or can include features having a number of different elements (e.g., components in a catalyst system or components in an olefin trimerization oligomerization process, among other features). This steps and/or elements can be designated utilizing the series a), b), c), etc., i), ii), iii), etc., (a), (b), (c), etc., and/or (i), (ii), (iii), etc. (among other designation series) as necessary to provide a designation for each process step and/or element. It should be understood that the numerical or alphabetical precedence of the designations within a designation series does not imply a particular order or preference of the process step in a process described herein, the feature(s) described herein, and/or an element(s) in a feature unless specifically specified otherwise or necessitated by other process steps, elements, and/or element features. Additionally, these designations series are provided to differentiate different process steps and/or elements in a feature and can be utilized as necessary, and without regard to the designation series utilized for a particular step, element, or feature utilized within this description as long as the designation series consistently distinguish different features, different process steps, and/or different elements of a feature.
The term “substantially anhydrous,” when referring to a compound, solution, solvent, or general conditions, means that the amount of water is less than or equal to 100 ppm (by weight) based upon the weight of the compound, solution, or solvent. The term “substantially dry,” when referring to an atmosphere, means that the atmosphere, regardless of the atmosphere's composition, means that the amount of water in the atmosphere is less than or equal to 100 ppm, by weight.
The term “acid-free” refers to process being carried out without the discrete addition of an acidic or protic compound or substance. For example, “acid-free” means that there has been no addition of a carboxylic acid, mineral or inorganic acid, alcohol, or other protic compounds or substances to the reaction or solution described as “acid-free.” The term “acid-free” is not intended to reflect a 0 ppm concentration of [H3O]+ or 0 ppm concentration of an acidic or protic source, as “acid-free” conditions still can reflect the presence of small amounts of acid that can exist as contaminants in an added component or can arise as a by-product during the course of the reaction or preparation of a reaction solution. For example, the transition metal carboxylate(s) and transition metal carboxylate composition(s) prepared by the disclosed methods can contain measurable amounts of free carboxylic acid, or other protogenic compounds that can arise as contaminants or as by-products during the preparation of such compounds or compositions. The term “substantially acid-free,” when referring to a compound, solution, solvent, or general conditions, means that the amount of acid is less than or equal to 1000 ppm (by weight) based upon the weight of the compound, solution, or solvent.
The terms “room temperature” or “ambient temperature” are used herein to describe any temperature from 15° C. to 35° C. wherein no external heat or cooling source is directly applied to the reaction vessel. Accordingly, the terms “room temperature” and “ambient temperature” encompass the individual temperatures and any and all ranges, subranges, and combinations of subranges of temperatures from 15° C. to 35° C. wherein no external heating or cooling source is directly applied to the reaction vessel.
The term “atmospheric pressure” is used herein to describe an earth air pressure wherein no external pressure modifying means is utilized. Generally, unless practiced at extreme earth altitudes, “atmospheric pressure” is about 1 atmosphere (alternatively, about 14.7 psi or about 101 kPa).
The term “aprotic” is used herein to describe a solvent that is non-protogenic under the given conditions. Thus, an “aprotic” compound or solvent is not capable of acting as a proton donor, either strongly or weakly acidic as a Brønsted acid, under the specific conditions. For example, acetonitrile can be an aprotic solvent even though it can be deprotonated in the presence of a strong base such as potassium tert-butoxide.
For any particular compound disclosed herein, the general structure or name presented is also intended to encompass all structural isomers, conformational isomers, and stereoisomers that can arise from a particular set of substituents, unless indicated otherwise. Thus, a general reference to a compound includes all structural isomers unless explicitly indicated otherwise; e.g., a general reference to pentane includes n-pentane, 2-methyl-butane, and 2,2-dimethylpropane while a general reference to a butyl group includes an n-butyl group, a sec-butyl group, an iso-butyl group, and a tert-butyl group. Additionally, the reference to a general structure or name encompasses all enantiomers, diastereomers, and other optical isomers whether in enantiomeric or racemic forms, as well as mixtures of stereoisomers, as the context permits or requires. For any particular formula or name that is presented, any general formula or name presented also encompasses all conformational isomers, regioisomers, and stereoisomers that can arise from a particular set of substituents.
A chemical “group” is described according to how that group is formally derived from a reference or “parent” compound, for example, by the number of hydrogen atoms formally removed from the parent compound to generate the group, even if that group is not literally synthesized in this manner. These groups can be utilized as substituents or coordinated or bonded to metal atoms. By way of example, an “alkyl group” formally can be derived by removing one hydrogen atom from an alkane, while an “alkylene group” formally can be derived by removing two hydrogen atoms from an alkane. Moreover, a more general term can be used to encompass a variety of groups that formally can be derived by removing any number (“one or more”) hydrogen atoms from a parent compound, which in this example can be described as an “alkane group,” and which encompasses an “alkyl group,” an “alkylene group,” and materials have three or more hydrogens atoms, as necessary for the situation, removed from the alkane. Throughout, the disclosure that a substituent, ligand, or other chemical moiety can constitute a particular “group” implies that the well-known rules of chemical structure and bonding are followed when that group is employed as described. When describing a group as being “derived by,” “derived from,” “formed by,” or “formed from,” such terms are used in a formal sense and are not intended to reflect any specific synthetic methods or procedure, unless specified otherwise or the context requires otherwise. Other identifiers or qualifying terms may be utilized to indicate the presence or absence of a particular substituent, a particular regiochemistry and/or stereochemistry, or the presence or absence of a branched underlying structure or backbone.
The term “substituted” when used to describe a group, for example, when referring to a substituted analog of a particular group, is intended to describe any non-hydrogen moiety that formally replaces a hydrogen in that group, and is intended to be non-limiting. A group or groups can also be referred to herein as “unsubstituted” or by equivalent terms such as “non-substituted,” which refers to the original group in which a non-hydrogen moiety does not replace a hydrogen within that group. “Substituted” is intended to be non-limiting and include inorganic substituents or organic substituents.

Acyclic phosphites are phosphites in which the phosphite phosphorus atom is not contained in a ring (but can have a ring, aliphatic or aromatic, as or within R12, R13, and/or R14). Cyclic phosphites are phosphites wherein the phosphite phosphorus atom is incorporated within a ring (either an aliphatic ring or aromatic ring). Aliphatic cyclic phosphites are cyclic phosphites wherein the phosphite phosphorus atom is incorporated within an aliphatic ring. Aromatic cyclic phosphites are phosphites wherein the phosphite phosphorus atom is incorporated within an aromatic ring or aromatic ring system.
The term “cyclic” as compared to an “acyclic” when referring to an ether, thioether, amine, phosphine, or phosphite is used to refer to a compound in which the heteroatom O, S, N, or P, respectively, is encompassed within a cyclic structure, which also encompasses the R2 and R3 groups of the ether R2—O—R3, the R4 and R5 groups of the thioether R4—S—R5, any combination of R6, R7, and R8 of the amine NR6R7R8 or NHR6R7, any combination of R9, R10, and R11 of the phosphine PR9R10R11 or PHR9R10, or any combination of R12, R11, and R14 of the phosphite P(OR12)(OR13)(OR14) or PH(O)(OR12)(OR13). For example, a “cyclic ether” is an analog of the acyclic ether structure R2—O—R3, in which R2 and R3 are generally as provided above in describing the (acyclic) ether R2—O—R3, except that R2 and R3 are linked or bonded to each other by removing a hydrogen atom from each of R2 and R3 and forming a bond between R2 and R3 where the hydrogen atoms were removed so as to form a cyclic structure that includes the ether oxygen. Tetrahydrofuran (THF) is a prototypical cyclic ether that can be formally derived by removing a hydrogen atom from each CH3 groups of diethyl ether (CH3CH2OCH2CH3) or a hydrogen atom from each CH3 groups of methyl n-propyl ether (CH3CH2CH2OCH3), followed by linking or bonding the two carbons from which the hydrogen atoms are removed. Similarly, the cyclic ether 2-methyloxetane can be formally derived by removing a hydrogen atom from the CH3 group of one ethyl group of ethyl ether and a hydrogen atom from the CH2 of the other ethyl group of diethyl ether (CH3CH2OCH2CH3), followed by a formal linking of the two carbons from which the hydrogen atoms are removed.
The term “organyl group” is used herein in accordance with the definition specified by IUPAC: an organic substituent group, regardless of functional type, having one free valence at a carbon atom. Similarly, an “organylene group” refers to an organic group, regardless of functional type, derived by removing two hydrogen atoms from an organic compound, either two hydrogen atoms from one carbon atom or one hydrogen atom from each of two different carbon atoms. An “organic group” refers to a generalized group formed by removing one or more hydrogen atoms from carbon atoms of an organic compound. Thus, an “organyl group,” an “organylene group,” and an “organic group” can contain organic functional group(s) and/or atom(s) other than carbon and hydrogen, that is, an organic group that can comprise functional groups and/or atoms in addition to carbon and hydrogen. For instance, non-limiting examples of atoms other than carbon and hydrogen can include, but is not limited to, halogens, oxygen, sulfur, nitrogen, and phosphorus, among other elements. Non-limiting examples of functional groups include ethers, aldehydes, ketones, esters, sulfides, amines, and phosphines, and so forth. In one aspect, the hydrogen atom(s) removed to form the “organyl group,” “organylene group,” or “organic group” can be attached to a carbon atom belonging to a functional group, for example, an acyl group (—C(O)R), a formyl group (—C(O)H), a carboxy group (—C(O)OH), a hydrocarboxycarbonyl group (—C(O)OR), a cyano group (—C≡N), a carbamoyl group (—C(O)NH2), a N-hydrocarbylcarbamoyl group (—C(O)NHR), or N,N′-dihydrocarbylcarbamoyl group (—C(O)NR2), among other possibilities. In another aspect, the hydrogen atom(s) removed to form the “organyl group,” “organylene group,” or “organic group” can be attached to a carbon atom not belonging to, and remote from, a functional group, for example, —CH2C(O)CH3, and —CH2NR2, among other elements. An “organyl group,” “organylene group,” or “organic group” can be aliphatic, inclusive of being cyclic or acyclic, or can be aromatic. “Organyl groups,” “organylene groups,” and “organic groups” also can encompass heteroatom-containing rings, heteroatom-containing ring systems, heteroaromatic rings, and heteroaromatic ring systems. “Organyl groups,” “organylene groups,” and “organic groups” can be linear or branched unless otherwise specified. Finally, it is noted that the “organyl group,” “organylene group,” or “organic group” definitions include “hydrocarbyl group,” “hydrocarbylene group,” “hydrocarbon group,” respectively, and “alkyl group,” “alkylene group,” and “alkane group,” respectively, as members.
The term “organyl group consisting of inert functional groups” refers to an organyl group wherein the organic functional group(s) and/or atom(s) other than carbon and hydrogen present in the functional group are restricted to those functional group(s) and/or atom(s) other than carbon and hydrogen which do not complex with a metal compound and/or are inert under the process conditions defined herein. Thus, the term or variation of the term “organyl groups consisting of inert functional groups” further defines the particular organyl groups that can be present within the organyl group consisting of inert functional groups. Additionally, the term “organyl group consisting of inert functional groups” can refer to the presence of one or more inert functional groups within the organyl group. The term or variation of the term “organyl group consisting of inert functional group” includes the hydrocarbyl group as a member. Similarly, an “organylene group consisting of inert functional groups” refers to an organic group formed by removing two hydrogen atoms from one or two carbon atoms of an organic compound consisting of inert functional groups and an “organic group consisting of inert functional group” refers to a generalized organic group consisting of inert functional groups formed by removing one or more hydrogen atoms from one or more carbon atoms of an organic compound consisting of inert functional groups.
For purposes of this application, an “inert functional group” is a group having a free valence on a heteroatom which does not substantially interfere with the process described herein in which the material having an inert functional group takes part and/or does not complex with the metal compound of the metal complex. The term “does not complex with the metal compound” can include groups that could complex with a metal compound but in particular molecules described herein may not complex with a metal compound due to its positional relationship within a ligand. Thus, the inertness of a particular functional group is not only related to the functional group's inherent inability to complex the metal compound but can also be related to the functional group's position within the metal complex. Non-limiting examples of inert functional groups which do not substantially interfere with processes described herein can include a halide (fluoride, chloride, bromide, and iodide), nitro, hydrocarboxy groups (e.g, alkoxy, and/or aroxy, among others), and/or hydrocarbosulfidyl groups (e.g., RS—), among others.
The term “hydrocarbon” whenever used in this specification and claims refers to a compound containing only carbon and hydrogen. Other identifiers can be utilized to indicate the presence of particular groups in the hydrocarbon (e.g. halogenated hydrocarbon indicates that the presence of one or more halogen atoms replacing an equivalent number of hydrogen atoms in the hydrocarbon). The term “hydrocarbyl group” is used herein in accordance with the definition specified by IUPAC: a univalent group formed by removing a hydrogen atom from a hydrocarbon (that is, a group containing only carbon and hydrogen). Non-limiting examples of hydrocarbyl groups include ethyl, phenyl, tolyl, propenyl, and the like. Similarly, a “hydrocarbylene group” refers to a group formed by removing two hydrogen atoms from a hydrocarbon, either two hydrogen atoms from one carbon atom or one hydrogen atom from each of two different carbon atoms. Therefore, in accordance with the terminology used herein, a “hydrocarbon group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group) from a hydrocarbon. A “hydrocarbyl group,” “hydrocarbylene group,” and “hydrocarbon group” can be acyclic or cyclic groups, and/or can be linear or branched. A “hydrocarbyl group,” “hydrocarbylene group,” and “hydrocarbon group” can include rings, ring systems, aromatic rings, and aromatic ring systems, which contain only carbon and hydrogen. “Hydrocarbyl groups,” “hydrocarbylene groups,” and “hydrocarbon groups” include, by way of example, aryl, arylene, arene groups, alkyl, alkylene, alkane group, cycloalkyl, cycloalkylene, cycloalkane groups, aralkyl, aralkylene, and aralkane groups, respectively, among other groups as members.
An aliphatic compound is an acyclic or cyclic, saturated or unsaturated, carbon compound, excluding aromatic compounds. An “aliphatic group” is a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group) from the carbon atom of an aliphatic compound. Aliphatic compounds and aliphatic groups can contain organic functional group(s) and/or atom(s) other than carbon and hydrogen.
The term “alkane” whenever used in this specification and claims refers to a saturated hydrocarbon compound. Other identifiers can be utilized to indicate the presence of particular groups in the alkane (e.g. halogenated alkane indicates that the presence of one or more halogen atoms replacing an equivalent number of hydrogen atoms in the alkane). The term “alkyl group” is used herein in accordance with the definition specified by IUPAC: a univalent group formed by removing a hydrogen atom from an alkane. Similarly, an “alkylene group” refers to a group formed by removing two hydrogen atoms from an alkane (either two hydrogen atoms from one carbon atom or one hydrogen atom from two different carbon atoms). An “alkane group” is a general term that refers to a group formed by removing one or more hydrogen atoms (as necessary for the particular group) from an alkane. An “alkyl group,” “alkylene group,” and “alkane group” can be acyclic or cyclic groups, and/or can be linear or branched unless otherwise specified. Primary, secondary, and tertiary alkyl group are derived by removal of a hydrogen atom from a primary, secondary, tertiary carbon atom, respectively, of an alkane. The n-alkyl group derived by removal of a hydrogen atom from a terminal carbon atom of a linear alkane. The groups RCH2 (where R is not H), R2CH (where R is not H), and R3C (where R is not H) are primary, secondary, and tertiary alkyl groups, respectively.
A “cycloalkane” is a saturated cyclic hydrocarbon, with or without side chains, for example, cyclobutane. Unsaturated cyclic hydrocarbons having one or more endocyclic double or one triple bond are called cycloalkenes and cycloalkynes, respectively. Cycloalkenes and cycloalkynes having only one, only two, only three, and so forth, endocyclic double or triple bonds can be identified by use of the term “mono,” “di,” “tri,” and so forth, within the name of the cycloalkene or cycloalkyne. Cycloalkenes and cycloalkynes can further identify the position of the endocyclic double or triple bonds. Other identifiers can be utilized to indicate the presence of particular groups in the cycloalkane (e.g. halogenated cycloalkane indicates the presence of one or more halogen atoms replacing an equivalent number of hydrogen atoms in the cycloalkane).
A “cycloalkyl group” is a univalent group derived by removing a hydrogen atom from a ring carbon atom of a cycloalkane. For example, a 1-methylcyclopropyl group and a 2-methylcyclopropyl group are illustrated as follows.




Similarly, a “cycloalkylene group” refers to a group derived by removing two hydrogen atoms from a cycloalkane, at least one of which is a ring carbon. Thus, a “cycloalkylene group” includes both a group derived from a cycloalkane in which two hydrogen atoms are formally removed from the same ring carbon, a group derived from a cycloalkane in which two hydrogen atoms are formally removed from two different ring carbons, and a group derived from a cycloalkane in which a first hydrogen atom is formally removed from a ring carbon and a second hydrogen atom is formally removed from a carbon atom that is not a ring carbon. A “cycloalkane group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is a ring carbon) from a cycloalkane. It should be noted that according to the definitions provided herein, general cycloalkane groups (including cycloalkyl groups and cycloalkylene groups) include those having zero, one, or more than one hydrocarbyl substituent groups attached to a cycloalkane ring carbon atom (e.g. a methylcyclopropyl group) and is member of the group of hydrocarbon groups. However, when referring to a cycloalkane group having a specified number of cycloalkane ring carbon atoms (e.g. cyclopentane group or cyclohexane group, among others), the base name of the cycloalkane group having a defined number of cycloalkane ring carbon atoms refers to the unsubstituted cycloalkane group (including having no hydrocarbyl groups located on cycloalkane group ring carbon atom). Consequently, a substituted cycloalkane group having a specified number of ring carbon atoms (e.g. substituted cyclopentane or substituted cyclohexane, among others) refers to the respective group having one or more substituent groups (including halogens, hydrocarbyl groups, or hydrocarboxy groups, among other substituent groups) attached to a cycloalkane group ring carbon atom. When the substituted cycloalkane group having a defined number of cycloalkane ring carbon atoms is a member of the group of hydrocarbon groups (or a member of the general group of cycloalkane groups), each substituent of the substituted cycloalkane group having a defined number of cycloalkane ring carbon atoms is limited to hydrocarbyl substituent group. One can readily discern and select general groups, specific groups, and/or individual substituted cycloalkane group(s) having a specific number of ring carbons atoms which can be utilized as member of the hydrocarbon group (or a member of the general group of cycloalkane groups).

The term “olefin” whenever used in this specification and claims refers to compounds that have at least one carbon-carbon double bond that is not part of an aromatic ring or ring system. The term “olefin” includes aliphatic and aromatic, cyclic and cyclic, and/or linear and branched compounds having at least one carbon-carbon double bond that is not part of an aromatic ring or ring system unless specifically stated otherwise. The term “olefin,” by itself, does not indicate the presence or absence of heteroatoms and/or the presence or absence of other carbon-carbon double bonds unless explicitly indicated. Olefins having only one, only two, only three, and so forth, carbon-carbon double bonds can be identified by use of the term “mono,” “di,” “tri,” and so forth, within the name of the olefin. The olefins can be further identified by the position of the carbon-carbon double bond(s).
The term “alkene” whenever used in this specification and claims refers to a hydrocarbon olefin that has at least one non-aromatic carbon-carbon double bond. The term “alkene” includes aliphatic or aromatic (an alkene having an aromatic substituent within the compound), cyclic or acyclic, and/or linear and branched compounds having at least one non-aromatic carbon-carbon double bond unless expressly stated otherwise. Alkenes having only one, only two, only three, and so forth, carbon double bonds can be identified by use of the term “mono,” “di,” “tri,” and so forth, within the name. For example, alkamonoenes, alkadienes, and alkatrienes refer to a linear or branched hydrocarbon olefins having only one carbon-carbon double bond (general formula CnH2n), only two carbon-carbon double bonds (general formula CnH2n-2), and only three carbon-carbon double bonds (general formula CnH2n-4), respectively. Alkenes can be further identified by the position of the carbon-carbon double bond(s). Other identifiers can be utilized to indicate the presence or absence of particular groups within an alkene. For example, a haloalkene refers to an alkene having one or more hydrogen atoms replace with a halogen atom.
An “alkenyl group” is a univalent group derived from an alkene by removal of a hydrogen atom from any carbon atom of the alkene. Thus, “alkenyl group” includes groups in which the hydrogen atom is formally removed from a sp2 hybridized (olefinic) carbon atom and groups in which the hydrogen atom is formally removed from any other carbon atom. For example and unless otherwise specified, propen-1-yl (—CH═CHCH3), propen-2-yl [(CH3)C═CH2], and propen-3-yl (—CH2CH═CH2) groups are all encompassed with the term “alkenyl group.” Similarly, an “alkenylene group” refers to a group formed by formally removing two hydrogen atoms from an alkene, either two hydrogen atoms from one carbon atom or one hydrogen atom from two different carbon atoms. An “alkene group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group) from an alkene. When the hydrogen atom is removed from a carbon atom participating in a carbon-carbon double bond, the regiochemistry of the carbon from which the hydrogen atom is removed, and regiochemistry of the carbon-carbon double bond can both be specified. Alkenyl groups can also have more than one such multiple bond. The alkene group can also be further identified by the position of the carbon-carbon double bond(s). Other identifiers can be utilized to indicate the presence or absence of particular groups within an alkene group. For example, a haloalkene group refers to an alkene group having one or more hydrogen atoms replaced with a halogen atom.
The term “alkyne” is used in this specification and claims to refer to a hydrocarbon compound that has at least one non-aromatic carbon-carbon triple bond. The term “alkyne” includes aliphatic or aromatic (an alkyne having an aromatic substituent within the compound), cyclic or acyclic, and/or linear and branched compounds having at least one non-aromatic carbon-carbon triple bond unless expressly stated otherwise. Alkynes having only one, only two, only three, and so forth, carbon-carbon triple bonds can be identified by use of the term “mono,” “di,” “tri,” and so forth, within the name. For example, alkamonoynes, alkadiynes, and alkatriynes refer to a linear or branched hydrocarbon olefins having only one carbon-carbon triple bond (general formula CnH2n-2), only two carbon-carbon triple bonds (general formula CnH2n-6), and only three carbon-carbon triple bonds (general formula CnH2n-10), respectively. Alkynes can be further identified by the position of the carbon-carbon triple bond(s). Other identifiers can be utilized to indicate the presence or absence of particular groups within an alkyne. For example, a haloalkyne refers to an alkyne having one or more hydrogen atoms replace with a halogen atom.
An “alkynyl group” is a univalent group derived from an alkyne by removal of a hydrogen atom from any carbon atom of the alkyne. Thus, “alkynyl group” includes groups in which the hydrogen atom is formally removed from a sp hybridized (acetylenic) carbon atom and groups in which the hydrogen atom is formally removed from any other carbon atom. For example and unless otherwise specified, propyn-1-yl (—C≡CCH3) and propyn-1-yl (HC≡CCH2—) groups are all encompassed with the term “alkynyl group.” Similarly, an “alkynylene group” refers to a group formed by formally removing two hydrogen atoms from an alkyne, either two hydrogen atoms from one carbon atom if possible or one hydrogen atom from two different carbon atoms. An “alkyne group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group) from an alkyne. Alkynyl groups can also have more than one such multiple bond. The alkyne group can also be further identified by the position of the carbon-carbon triple bond(s). Other identifiers can be utilized to indicate the presence or absence of particular groups within an alkyne group. For example, a haloalkyne group refers to an alkyne group having one or more hydrogen atoms replaced with a halogen atom.
A “heterocyclic compound” is a cyclic compound having at least two different elements as ring member atoms. For example, heterocyclic compounds can comprise rings containing carbon and nitrogen (for example, tetrahydropyrrole and pyrrole, among others), carbon and oxygen (for example, tetrahydrofuran and furan, among others), or carbon and sulfur (for example, tetrahydrothiophene and thiophene, among others). Heterocyclic compounds and heterocyclic groups can be either aliphatic or aromatic.
A “heterocyclyl group” is a univalent group formed by removing a hydrogen atom from a heterocyclic ring or ring system carbon atom of a heterocyclic compound. By specifying that the hydrogen atom is removed from a heterocyclic ring or ring system carbon atom, a “heterocyclyl group” is distinguished from a “cycloheteryl group,” in which a hydrogen atom is removed from a heterocyclic ring or ring system heteroatom. For example, a pyrrolidin-2-yl group illustrated below is one example of a “heterocyclyl group,” and a pyrrolidin-1-yl group illustrated below is one example of a “cycloheteryl” group.”




Similarly, a “heterocyclylene group” or more simply, a “heterocyclene group,” refers to a group formed by removing two hydrogen atoms from a heterocyclic compound, at least one of which is from a heterocyclic ring or ring system carbon. Thus, in a “heterocyclylene group,” at least one hydrogen is removed from a heterocyclic ring or ring system carbon atom, and the other hydrogen atom can be removed from any other carbon atom, including for example, the same heterocyclic ring or ring system carbon atom, a different heterocyclic ring or ring system ring carbon atom, or a non-ring carbon atom. A “heterocyclic group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is a heterocyclic ring carbon atom) from a heterocyclic compound.

A “cycloheteryl group” is a univalent group formed by removing a hydrogen atom from a heterocyclic ring or ring system heteroatom of a heterocyclic compound, as illustrated herein. By specifying that the hydrogen atom is removed from a heterocyclic ring or ring system heteroatom and not from a ring carbon atom, a “cycloheteryl group” is distinguished from a “heterocyclyl group” in which a hydrogen atom is removed from a heterocyclic ring or ring system carbon atom. Similarly, a “cycloheterylene group” refers to a group formed by removing two hydrogen atoms from an heterocyclic compound, at least one of which is removed from a heterocyclic ring or ring system heteroatom of the heterocyclic compound; the other hydrogen atom can be removed from any other atom, including for example, a heterocyclic ring or ring system ring carbon atom, another heterocyclic ring or ring system heteroatom, or a non-ring atom (carbon or heteroatom). A “cyclohetero group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is from a heterocyclic ring or ring system heteroatom) from a heterocyclic compound.
An aromatic compound is a compound containing a cyclically conjugated double bond system that follows the Hückel (4n+2) rule and contains (4n+2) pi-electrons, where n is an integer from 1 to 5. Aromatic compounds include “arenes” (hydrocarbon aromatic compounds) and “heteroarenes,” also termed “hetarenes” (heteroaromatic compounds formally derived from arenes by replacement of one or more methine (—C═) carbon atoms of the cyclically conjugated double bond system with a trivalent or divalent heteroatoms, in such a way as to maintain the continuous pi-electron system characteristic of an aromatic system and a number of out-of-plane pi-electrons corresponding to the Hückel rule (4n+2). While arene compounds and heteroarene compounds are mutually exclusive members of the group of aromatic compounds, a compound that has both an arene group and a heteroarene group are generally considered a heteroarene compound. Aromatic compounds, arenes, and heteroarenes can be monocyclic (e.g., benzene, toluene, furan, pyridine, methylpyridine) or polycyclic unless otherwise specified. Polycyclic aromatic compounds, arenes, and heteroarenes, include, unless otherwise specified, compounds wherein the aromatic rings can be fused (e.g., naphthalene, benzofuran, and indole), compounds where the aromatic groups can be separate and joined by a bond (e.g., biphenyl or 4-phenylpyridine), or compounds where the aromatic groups are joined by a group containing linking atoms (e.g., carbon—the methylene group in diphenylmethane; oxygen—diphenyl ether; nitrogen-triphenyl amine; among other linking groups). As disclosed herein, the term “substituted” can be used to describe an aromatic group, an arene, or a heteroarene wherein a non-hydrogen moiety formally replaces a hydrogen in the compound, and is intended to be non-limiting.
An “aromatic group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is an aromatic ring carbon atom) from an aromatic compound. For a univalent “aromatic group,” the removed hydrogen atom must be from an aromatic ring carbon. For an “aromatic group” formed by removing more than one hydrogen atom from an aromatic compound, at least one hydrogen atom must be from an aromatic hydrocarbon ring carbon. Additionally, an “aromatic group” can have hydrogen atoms removed from the same ring of an aromatic ring or ring system (e.g., phen-1,4-ylene, pyridin-2,3-ylene, naphth-1,2-ylene, and benzofuran-2,3-ylene), hydrogen atoms removed from two different rings of a ring system (e.g., naphth-1,8-ylene and benzofuran-2,7-ylene), or hydrogen atoms removed from two isolated aromatic rings or ring systems (e.g., bis(phen-4-ylene)methane).
An arene is an aromatic hydrocarbon, with or without side chains (e.g. benzene, toluene, or xylene, among others). An “aryl group” is a group derived from the formal removal of a hydrogen atom from an aromatic ring carbon of an arene. It should be noted that the arene can contain a single aromatic hydrocarbon ring (e.g., benzene, or toluene), contain fused aromatic rings (e.g., naphthalene or anthracene), and contain one or more isolated aromatic rings covalently linked via a bond (e.g., biphenyl) or non-aromatic hydrocarbon group(s) (e.g., diphenylmethane). One example of an “aryl group” is ortho-tolyl (o-tolyl), the structure of which is shown here.




Similarly, an “arylene group” refers to a group formed by removing two hydrogen atoms (at least one of which is from an aromatic ring carbon) from an arene. An “arene group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is an aromatic ring carbon) from an arene. However, if a group contains separate and distinct arene and heteroarene rings or ring systems (e.g. the phenyl and benzofuran moieties in 7-phenylbenzofuran) its classification depends upon the particular ring or ring system from which the hydrogen atom was removed, that is, an arene group if the removed hydrogen came from the aromatic hydrocarbon ring or ring system carbon atom (e.g. the 2 carbon atom in the phenyl group of 6-phenylbenzofuran) and a heteroarene group if the removed hydrogen carbon came from a heteroaromatic ring or ring system carbon atom (e.g. the 2 or 7 carbon atom of the benzofuran group or 6-phenylbenzofuran). It should be noted that according the definitions provided herein, general arene groups (including an aryl group and an arylene group) include those having zero, one, or more than one hydrocarbyl substituent groups located on an aromatic hydrocarbon ring or ring system carbon atom (e.g. a toluene group or a xylene group, among others) and is a member of the group of hydrocarbon groups. However, a phenyl group (or phenylene group) and/or a naphthyl group (or naphthylene group) refer to the specific unsubstituted arene groups (including no hydrocarbyl group located on an aromatic hydrocarbon ring or ring system carbon atom). Consequently, a substituted phenyl group or substituted naphthyl group refers to the respective arene group having one or more substituent groups (including halogens, hydrocarbyl groups, or hydrocarboxy groups, among others) located on an aromatic hydrocarbon ring or ring system carbon atom. When the substituted phenyl group and/or substituted naphthyl group is a member of the group of hydrocarbon groups (or a member of the general group of arene groups), each substituent is limited to a hydrocarbyl substituent group. One can readily discern and select general substituted phenyl and/or substituted naphthyl groups, specific substituted phenyl and/or substituted naphthyl groups, and/or individual substituted phenyl or substituted naphthyl groups which can be utilized as a member of the group of hydrocarbon groups (or a member of the general group of arene groups).

A heteroarene is aromatic compound, with or without side chains, having a heteroatom within the aromatic ring or aromatic ring system (e.g. pyridine, indole, or benzofuran, among others). A “heteroaryl group” is a class of “heterocyclyl group” and is a univalent group formed by removing a hydrogen atom from a heteroaromatic ring or ring system carbon atom of a heteroarene compound. By specifying that the hydrogen atom is removed from a ring carbon atom, a “heteroaryl group” is distinguished from an “arylheteryl group,” in which a hydrogen atom is removed from a heteroaromatic ring or ring system heteroatom. For example, an indol-2-yl group illustrated below is one example of a “heteroaryl group,” and an indol-1-yl group illustrated below is one example of an “arylheteryl” group.”




Similarly, a “heteroarylene group” refers to a group formed by removing two hydrogen atoms from a heteroarene compound, at least one of which is from a heteroarene ring or ring system carbon atom. Thus, in a “heteroarylene group,” at least one hydrogen is removed from a heteroarene ring or ring system carbon atom, and the other hydrogen atom can be removed from any other carbon atom, including for example, a heteroarene ring or ring system carbon atom, or a non-heteroarene ring or ring system atom. A “heteroarene group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is a heteroarene ring or ring system carbon atom) from a heteroarene compound. If a hydrogen atom is removed from a heteroaromatic ring or ring system heteroatom and from a heteroaromatic ring or ring system carbon atom or an aromatic hydrocarbon ring or ring system carbon atom, the group is classified as an “arylheterylene group” or an “arylhetero group.”

An “arylheteryl group” is a class of “cycloheteryl group” and is a univalent group formed by removing a hydrogen atom from a heteroaromatic ring or ring system heteroatom, as illustrated. By specifying that the hydrogen atom is removed from of a heteroaromatic ring or ring system heteroatom and not from a heteroaromatic ring or ring system carbon atom, an “arylheteryl group” is distinguished from a “heteroaryl group” in which a hydrogen atom is removed from a heteroaromatic ring or a ring system carbon atom. Similarly, an “arylheterylene group” refers to a group formed by removing two hydrogen atoms from a heteroaryl compound, at least one of which is removed from a heteroaromatic ring or ring system heteroatom of the heteroaryl compound; the other hydrogen atom can be removed from any other atom, including for example, a heteroaromatic ring or ring system carbon atom, another heteroaromatic ring or ring system heteroatom, or a non-ring atom (carbon or heteroatom) from a heteroaromatic compound. An “arylhetero group” refers to a generalized group formed by removing one or more hydrogen atoms (as necessary for the particular group and at least one of which is from a heteroaromatic ring or ring system) heteroatom from a heteroarene compound.
An “aralkyl group” is an aryl-substituted alkyl group having a free valance at a non-aromatic carbon atom (e.g. a benzyl group, or a 2-phenyleth-1-yl group, among others). Similarly, an “aralkylene group” is an aryl-substituted alkylene group having two free valencies at a single non-aromatic carbon atom or a free valence at two non-aromatic carbon atoms while an “aralkane group” is a generalized is an aryl-substituted alkane group having one or more free valencies at a non-aromatic carbon atom(s). A “heteroaralkyl group” is a heteroaryl-substituted alkyl group having a free valence at a non-heteroaromatic ring or ring system carbon atom. Similarly a “heteroaralkylene group” is a heteroaryl-substituted alkylene group having two free valencies at a single non-heteroaromatic ring or ring system carbon atom or a free valence at two non-heteroaromatic ring or ring system carbon atoms while a “heteroaralkane group” is a generalized aryl-substituted alkane group having one or more free valencies at a non-heteroaromatic ring or ring system carbon atom(s). It should be noted that according the definitions provided herein, general aralkane groups include those having zero, one, or more than one hydrocarbyl substituent groups located on an aralkane aromatic hydrocarbon ring or ring system carbon atom and is a member of the group of hydrocarbon groups. However, specific aralkane groups specifying a particular aryl group (e.g. the phenyl group in a benzyl group or a 2-phenylethyl group, among others) refer to the specific unsubstituted aralkane groups (including no hydrocarbyl group located on the aralkane aromatic hydrocarbon ring or ring system carbon atom). Consequently, a substituted aralkane group specifying a particular aryl group refers to a respective aralkane group having one or more substituent groups (including halogens, hydrocarbyl groups, or hydrocarboxy groups, among others). When the substituted aralkane group specifying a particular aryl group is a member of the group of hydrocarbon groups (or a member of the general group of aralkane groups), each substituent is limited to a hydrocarbyl substituent group. One can readily discern and select substituted aralkane groups specifying a particular aryl group which can be utilized as a member of the group of hydrocarbon groups (or a member of the general group of aralkane groups).
A “halide” has its usual meaning; therefore, examples of halides include fluoride, chloride, bromide, and iodide.
An “organoheteryl group” is a univalent group containing carbon, which are thus organic, but which have their free valence at an atom other than carbon. Thus, organoheteryl and organyl groups are complementary and mutually exclusive. Organoheteryl groups can be cyclic or acyclic, and/or aliphatic or aromatic, and thus encompasses aliphatic “cycloheteryl groups” (e.g. pyrrolidin-1-yl or morpholin-1-yl, among others), aromatic “arylheteryl groups” (e.g. pyrrol-1-yl or indol-1-yl, among others), and acyclic groups (e.g. organylthio, trihydrocarbylsilyl, aryloxy, or alkoxy, among others). Similarly, an “organoheterylene group” is a divalent group containing carbon and at least one heteroatom having two free valencies, at least one of which is at a heteroatom. An “organohetero group” is a generalized group containing carbon and at least one heteroatom having one or more free valencies (as necessary for the particular group and at least one of which is at a heteroatom) from an organohetero compound.
If a compound or group contains more than one moiety it is formally a member of the group having the highest naming priority as stipulated by IUPAC. For example 4-phenylpyridine is a heteroaromatic compound and a 4-(phen-2-ylene)pyridin-2-yl group is heteroaromatic group because the highest naming group is the pyridine group and the pyridin-2-yl group respectively.
In some instances, reference can be made to “cyclic groups.” Unless otherwise specified, “cyclic groups” include aromatic and aliphatic groups having a ring structure, including homocyclic and heterocyclic groups, and “cyclo” is a prefix used in names to designate a ring structure.

In other non-limiting aspects, this disclosure provides for chromium carboxylate compositions in which the carboxylate can be, comprise, or consist essentially of, a monocarboxylate having the formula −O2CR2c, wherein R2c is a C2 to C24 organyl group.

Other aspects and embodiments for the transition metal carboxylate compositions and/or chromium carboxylate compositions are readily apparent and contemplated from the present disclosure. In an aspect the transition metal carboxylate and/or chromium carboxylate composition can be, comprise, or consist essentially of, a chromium carboxylate composition produced by any process described herein.
It can be observed that the isolated transition metal carboxylate compositions of the present disclosure can appear more crystalline in nature the amorphous mass isolated from commercially available transition metal carboxylate compositions. For example, compare the isolated chromium(III) 2-ethylhexanoate of the present disclosure using a sodium 2-ethylhexanoate to CrCl3(THF)3 molar ratio of approximately 3.3 (FIG. 1) to an isolated commercially available chromium(III) 2-ethylhexanoate (FIG. 2). However, even after attempting several different crystallization methods, the transition metal carboxylate of the present invention does not form crystals which will allow the elucidation of their structure by traditional X-ray crystallography methods. Consequently, the transition metal carboxylate compositions of the present disclosure need to be distinguished from the present commercially available transition metal carboxylate compositions utilizing one or a combination of more than one other analytical technique.
One technique that can be utilized to distinguish the transition metal carboxylate of the present disclosure from other transition metal carboxylate compositions can be infrared spectroscopy. Another technique which can be utilized to distinguish the transition metal carboxylate of the present disclosure from other transition metal carboxylate compositions can be high energy X-ray diffraction. Particular features associated with infrared spectroscopy and high energy X-ray diffraction are independently described herein and any one or more of these features can be used either individually or in any combination to describe the transition metal carboxylates of the present disclosure.
Spectroscopic analysis of the transitional metal carboxylate composition, particularly infrared (IR) absorption spectroscopy, can provide useful characterization information related to the composition. Aspects of the IR spectra of carboxylate compositions are provided in K. Nakamoto, Infrared and Raman Spectra of Inorganic and Coordination Compounds, 4th Ed., J. Wiley & Sons, New York, c. 1986, pp. 231-233. Additionally, Cannon and White (Cannon, R. D and White R. P, Progress in Inorganic Chemistry; Volume 36, 1988, pp. 195-298) and Deacon and Phillips (G. B. Deacon and R. J. Phillips, Coordination Chemistry Reviews, 33 (1980), pp. 227-250) provide further information regarding the coordination of the carboxylate anion with transition metal and the IR spectra of transition metal carboxylates. Vlachos et al. (A. Vlachos, Psycharis, C. P. Raptopoula, N. Lalioti, Y. Sanakis, G. Diamantopoulos, M. Fardis, M. Karayanni, G. Papavassiliou, and A. Terzis, Inorganic Chimica Acta, 357 (2004), pp. 3162-3172), herein referred to as Vlachos, provides IR information about trinuclear chromium(III) oxo carboxylates. The entirety of Cannon and White, Deacon and Phillips, and Vlachosare each incorporated herein by reference for all purposes.
These articles indicate, without being limited to theory, that the υasym (CO2) IR peak locations for transition metal compounds in which the oxygen atoms of the carboxylate group bridge two transition metal atoms differ from those wherein the oxygen atoms of the carboxylate group are both bound to the same transition metal atom. Additionally, without being limited to theory, the separation between the υasym (CO2) IR peak(s) and the υsym (CO2) IR peak of transition metal carboxylate compounds in which the oxygen atoms of the carboxylate group bridge two transition metal atoms and those wherein the oxygen atoms of the carboxylate group are both bound to the same transition metal atom varies in a discernable manner. In particular, the υasym (CO2) IR peak location for transition metal compounds in which the oxygen atoms of the carboxylate group bond to the same transition metal atom occurs at lower wavenumber than the υasym (CO2) IR peak locations for transition metal compounds in which the oxygen atoms of the carboxylate group bond bridge to two transition metal atoms. Additionally, the separation between the υasym (CO2) IR peak(s) and the υsym (CO2) IR peak of the transition metal compounds in which the oxygen atoms of the carboxylate group bond to the same transition metal atom occurs is smaller than that of the transition metal compounds in which the oxygen atoms of the carboxylate group bond bridge to two transition metal atoms.
These articles also point out that transition metal carboxylate compositions contain species wherein multiple transition metals are bound to a single oxygen atoms. One such species which can be present, without being limited to theory, is the triangular bridged metal complexes having a MO3 unit described in Cannon and White and that the MO3 unit (where M is the transition metal) has a υasym (MO3) IR peak in the range of 750 cm−1 to 500 cm−1. For chromium triangular bridged complexes, the υsym (CrO3) IR peak appears around 750 cm−1 to 650 cm−1.
FIG. 4 and FIG. 6 provide the 2000 cm−1 to 1000 cm−1 portion of the IR spectrum for two commercially available chromium(III) 2-ethylhexanoate compositions. Each of these IR spectra show υasym (CO2) IR peaks at 1616±20 cm−1 and 1549±15 cm−1 respectively and a υsym (CO2) IR peak 1429±15 cm−1. FIG. 8, FIG. 10, FIG. 12, and FIG. 14 provide the 2000 cm−1 to 1000 cm−1 portion of the IR spectrum for four chromium(III) 2-ethylhexanoate compositions of the present disclosure. Each of these IR spectra show the presence of a υasym (CO2) IR peaks at 1516±15 cm−1, a υsym (CO2) IR peak 1429±15 cm−1, and significantly diminished υasym (CO2) IR peaks (if the peaks are even present) at 1616±20 cm−1 and 1549±15 cm−1. These IR spectra show that the transition metal carboxylate compositions of the present disclosure are significantly different from the transition metal carboxylate compositions which are presently commercially available.

In an embodiment, these IR peak related features can be determined by subjecting the chromium(III) carboxylate composition (or any other transition metal carboxylate composition described herein) contained in KBr (KBr pellet) to infrared analysis. Alternatively, if the chromium(III) carboxylate composition (or any other transition metal carboxylate composition described herein) is not suitable for analysis in a KBr pellet, the IR analysis can be performed by placing the transition metal carboxylate composition in a solvent or a dispersing agent that is IR transparent in the necessary IR peak regions (e.g. a mineral oil such as Nujol, among others). Additionally, the IR peak height ratio features can be based upon the raw peak heights or baseline corrected peak heights.
Generally, X-ray crystallography can be utilized to characterize the materials which form well defined crystals. However, in some instances, materials which one having ordinary skill in the art would believe to form well defined crystals do not form crystals which are suitable for traditional X-ray crystallography. For example, commercially available chromium(III) 2-ethylhexanoate forms an amorphous mass which is not suitable for traditional X-ray crystallography (see FIG. 2). Similarly, the chromium(III) 2-ethylhexanoate prepared using the methods described herein can form an amorphous mass (see FIG. 1); the produced chromium(III) 2-ethylhexanoate was a green tacky solid, showed no evidence of crystallinity, and was not suitable for traditional X-ray crystallography. In some of these instances, high energy X-ray diffraction can be utilized to provide structural information about the material. The high energy X-ray diffraction data for these materials can be compared to high energy X-ray diffraction data of other materials or to calculated high energy diffraction data of theoretical models of materials to determine the material's structure and/or whether or not the material is similar to other known materials.
In some embodiments, any transition metal carboxylate composition (general or specific) described herein or any transition metal carboxylate composition prepared by any process(es) described herein can be analyzed by high energy X-ray diffraction to determine the structure or structures of the transition metal carboxylate molecule(s) present in the transition metal carboxylate composition and/or compared to calculated high energy diffraction data of theoretical models of materials believed to be present in the transition metal carboxylate composition. For example, “Synthesis and structural studies of metal (Cr, Zn and Bi) carboxylate liquids” R. T. Hart Jr., N. A. Eckert, J. K. Ngala, A. F. Polley, C. J. Benmore, A. Clark, S. Macha, Presentation CATL 20, The 237th ACS National Meeting, Salt Lake City, Utah, Mar. 23, 2009, compared high energy X-ray diffraction g(r) data points of an aqueous metathesis process and displacement process produced chromium(III) carboxylate to the theoretical high energy X-ray diffraction g(r) data points of models of Cr3O(O2CCH3)6, Cr8(OH)8(O2CCH3)12, and Cr12O(O2CCH3)6, constructed from data presented in M. Eshel, et al., Inorg. Chem., 2000, 39, pp 1376, and M. Eshel, et al., Inorg Chim. Acta, 2002, 329, pp 45. The entirety of Hart Jr. et al. and M. Eshel et al. are incorporated herein by reference.
Without being limited to theory, it is believed that the transition metal carboxylate composition(s) described herein or prepared according to any process(es) disclosed herein can contain substantial quantities of mononuclear transition metal carboxylate. To test this hypothesis, one can compare the high energy X-ray diffraction g(r) data points for any transition metal carboxylate composition described herein or any transition metal carboxylate composition prepared according to any process(es) disclosed herein to the high energy X-ray diffraction g(r) data points for the authentic mononuclear transition metal carboxylate. In many instances pure and/or authentic samples of mononuclear transition metal carboxylates are not available. In these instances, the high energy X-ray diffraction g(r) data points for any transition metal carboxylate composition described herein or any transition metal carboxylate composition prepared according to any process(es) disclosed herein can be compared to a calculated high energy X-ray diffraction g(r) data points of a theoretical model of the mononuclear transition metal carboxylate. The model of the mononuclear transition metal carboxylate can be produced utilizing any number of methods available to those skilled in the art. In one example, the model of a mononuclear chromium(III) carboxylate can be obtained by using Spartan 08 with optimizations that assume a high spin Cr(III) center with quartet ground spin state by obtaining initial geometries via PM3 geometry optimizations with conformational searching and further geometry optimization utilized DFT B3LYP with the LACVP basis set with an effective core potential on Cr and 6-31 g** on H, C, O. In another example, the model of the mononuclear transition metal carboxylate can be obtained using a heuristic method similar to the one described herein for chromium(III) carboxylates. The high energy X-ray diffraction g(r) data points calculated for the mononuclear transition metal carboxylate model can be calculated using methods and/or programs available to those skilled in the art (e.g. the PDFFit library of functions and routines as implemented in PDFgui—version 1.0—C. L. Farrow, P. Juhás, J. W. Liu, D. Bo{hacek over (z)}in, E. S. Bolin, J. Bloch, Th. Proffen and S. J. L. Billinge, PDFfit2 and PDFgui: computer programs for studying nanostructure in crystals, J. Phys.: Condens. Matter 19, 335219 (2007)) and can be utilized to calculate the high energy X-ray diffraction d(r) data points for a mononuclear chromium carboxylate model which can then be converted to high energy X-ray diffraction g(r) data points.
The comparison of the high energy X-ray diffraction g(r) data points for transition metal carboxylate compositions described herein or prepared according to the process(es) disclosed herein to the high energy X-ray diffraction g(r) data points for the authentic mononuclear transition metal carboxylate or a calculated high energy X-ray diffraction g(r) data points of a theoretical model of the mononuclear transition metal carboxylate can be made using techniques known and used by those skilled in the art. One method for comparing the high energy X-ray diffraction g(r) data points for transition metal carboxylate compositions described herein or prepared according to the process(es) disclosed herein to the high energy X-ray diffraction g(r) data points for the authentic mononuclear transition metal carboxylate or a calculated high energy X-ray diffraction g(r) data points of a theoretical model(s) of the mononuclear transition metal carboxylate can be to perform a goodness of fit test. The closer the goodness of fit test test value, R2, is to 1, the more likely the transition metal carboxylate composition contains a significant quantity of mononuclear transition metal carboxylate.
It should be noted that when the comparison is made using a calculated high energy X-ray diffraction g(r) data points of a theoretical model of the mononuclear transition metal carboxylate, one does not necessarily expect a goodness of fit R2 test value very close to 1 because the comparison is made to a theoretical model of the mononuclear transition metal carboxylate and as such is not the actual structure for the mononuclear transition metal carboxylate. While not wishing to be bound by theory, it is believed that even if any of the herein described transition metal carboxylate compositions or any of the transition metal carboxylate compositions produced by any process(es) described herein is a pure mononuclear transition metal carboxylate, the goodness of fit R2 test value would unlikely be 1 because there could likely be differences between the structure of the theoretical model of the mononuclear transition metal carboxylate and the actual pure mononuclear transition carboxylate. The difference between these structures could result in differences in the measured high energy X-ray diffraction g(r) data points and the calculated high energy X-ray diffraction g(r) data points. Consequently, the goodness of fit test value, R2, would not be expected to be 1. However, the goodness of fit test value, R2, still has value since the high energy X-ray diffraction g(r) data points for transition metal carboxylate compositions having significant quantities of mononuclear transition metal carboxylate will have a goodness of fit test value, R2, closer to 1 than a transition metal carboxylate composition which has significant quantities of dinuclear, trinuclear, or higher polynuclear transition metal carboxylate species.
Depending upon the number of carbon atoms in the carboxylate of the transition metal carboxylate, it can be impractical or difficult to prepare a theoretical model of the mononuclear transition metal carboxylate. Reviewing theoretical structures of mononuclear transition metal carboxylates, it can be apparent that the transition metal atom, the two oxygen atoms of the carboxylate group chelated with the transition metal, the carboxylate group carbon and oxygen atoms, and the carbon atom attached to the carboxylate group can be relatively fixed in space because they do not have free rotation about any bond that could change its distance from the other atoms. Consequently, one could expect that there could not be large variations in the respective bond distances and bond angles between these atoms as a function of the carboxylate of the transition metal carboxylate. Without any further substituents, these atoms could form a transition metal acetate. Consequently, in an embodiment, any transition metal carboxylate composition described herein or any transition metal carboxylate composition produced by any process described herein can be compared to a mononuclear transition metal acetate. If any transition metal carboxylate composition described herein or any transition metal carboxylate composition produced by any process(es) described herein contains significant quantities of mononuclear transition metal carboxylate, one could expect that the high energy X-ray diffraction g(r) data points of a mononuclear transition metal carboxylate composition can be compared to the high energy X-ray diffraction g(r) data points of an authentic transition metal acetate or the calculated high energy X-ray diffraction g(r) data points of a theoretical model of the mononuclear transition metal transition metal acetate. Without being limited to theory, the comparison between any transition metal carboxylate composition described herein or any transition metal carboxylate composition produced by any process(es) described herein could be expected to be fairly similar to the high energy X-ray diffraction g(r) data points of an authentic transition metal acetate or a calculated high energy X-ray diffraction g(r) data points of a theoretical model of the mononuclear transition metal transition metal acetate. In particular, the comparison could be expected to be reasonable up to and including r values of 4 Å where the contributions from intermolecular interactions and contributions of the non-hydrogen atoms of the carboxylate group beyond the carbon atom attached to the carboxylate (C═O) carbon atom could be expected to be small.
Regarding the goodness of fit test value, R2, the goodness of fit test value can be calculated using the equation R2=1−(SSerr/SStot). Within the equation R2=1−(SSerr/SStot), SSer, is the summation of the squares of the residual between the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and either a) the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or b) the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate. Within the equation R2=1−(SSerr/SStot), SStot is the summation of the squares of the differences between the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the mean of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition. In order for the goodness of fit test value to have reasonable meaning, the test should be performed using a reasonable number of high energy X-ray diffraction g(r) data points. Herein, the goodness of fit test value can be calculated using high energy X-ray diffraction g(r) data points separated by 0.01 Angstroms over the r value range to which the goodness of fit test value is to be calculated. Typically, the high energy X-ray diffraction g(r) data points can be at exact hundredths of an Angstrom r values. However, the high energy X-ray diffraction g(r) data points can be based upon any set of g(r) data points separated by r values of 0.01 Angstroms. Additionally, to provide the best basis for the goodness of fit test value (and to avoid interpolation of the g(r) data points), the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data for a theoretical model of the mononuclear transition metal carboxylate should located at the same r values.
In an embodiment, the goodness of fit test value can be based on the application of the goodness of fit test over a range of r values of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate. In some embodiments, the minimum r value for the range of values for the goodness of fit test value for the comparison of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate can be 1.2 angstroms; alternatively, 1.25 angstroms; alternatively, 1.3 angstroms; alternatively, 1.35 angstroms; or alternatively, 1.4 angstroms. In some embodiments, the maximum r value for the range of values for the goodness of fit test value for the comparison of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate can be 4 angstroms; alternatively, 3.9 angstroms; alternatively, 3.8 angstroms; alternatively, 3.7 angstroms; or alternatively, 3.6 angstroms; alternatively, 3.5 angstroms; alternatively, 3.4 angstroms; alternatively, 3.3 angstroms; alternatively, 3.2 angstroms; alternatively, 3.1 angstroms; or alternatively, 3.0 angstroms. In an embodiment, the goodness of fit test value can be based upon the application of the goodness of fit test for the comparison of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate over an r value range that ranges from any minimum r value described herein to any maximum r value described herein. In some non-limiting embodiments, the goodness of fit test value can based upon the application of the goodness of fit test for the comparison of the high energy X-ray diffraction g(r) data points of the transition metal carboxylate composition and the high energy X-ray diffraction g(r) data points for the actual mononuclear transition metal carboxylate or the calculated high energy X-ray diffraction g(r) data points for a theoretical model of the mononuclear transition metal carboxylate over a r value range of 1.3 Angstroms to 4 Angstroms; or alternatively, the goodness of fit test value is based upon the application of the goodness of fit test over a r value range of 1.3 Angstroms to 3.2 Angstroms; alternatively, 1.3 Angstroms to 3.3 Angstroms; alternatively, 1.3 Angstroms to 3.4 Angstroms; alternatively, 1.3 Angstroms to 3.5 Angstroms; alternatively, 1.3 Angstroms to 3.6 Angstroms; alternatively, 1.3 Angstroms to 3.7 Angstroms; alternatively, 1.3 Angstroms to 3.8 Angstroms; alternatively, 1.3 Angstroms to 3.9 Angstroms; alternatively, 1.3 Angstroms to 4.0 Angstroms.
The r values of these ranges can seem arbitrary. However, the selection of the maximum r value of the ranges can be based upon supposition, without being limited to theory, that intermolecular contributions and effects of bond rotation beyond the carbon atom attached to the carboxylate (C═O) carbon atom cannot be accurately accounted for when using a calculated high energy X-ray diffraction of transition metal carboxylate theoretical model. Thus the longer r value can be selected to exclude these difficult to model characteristics. The lower limit of the r value of these ranges can be based upon the supposition, without being limited to theory, that the more important and/or more meaningful atom to atom distances can have an average atom to atom distance of at least 1.2 to 1.3 angstroms. Additionally, the only bond distances shorter than 1.2 Angstroms are then carbon-hydrogen bonds which contribute less than 1 percent to the scattering intensity and are not generally considered in the data handling and modeling. Thus, the lower limit of the shorter r value can be selected to include the contributions from the shortest important and/or meaningful atom to atom distances.

EXAMPLES
General Experimental Procedures and Starting Materials
Unless specified otherwise, all reactions were performed under an inert and at least substantially dry atmosphere. All glassware was dried in an oven at 100° C. for 4 hr and brought into an inert and at least substantially dry atmosphere glovebox (drybox) while warm.
The starting material CrCl3(THF)3 was purchased from Aldrich Chemical Company and dried further as described below. The 2-ethylhexanoic acid was purchased from Aldrich and used without further purification. All solvents were purchased from Aldrich as anhydrous grade and were stored over freshly activated 5 Å molecular sieves.
Example 1
A round bottom flask (250 mL) was charged with a stir bar, sodium hydroxide (13.87 g, 0.347 mol) and methanol (200 mL) under ambient conditions. 2-Ethylhexanoic acid (50.00 g, 0.347 mol) was added dropwise to the stirred solution over 30 min. The solvent was then removed by rotary evaporation producing a white, tacky solid. This white solid was then heated at 185° C. and a pressure less that 25 torr for 18 hr, yielding anhydrous sodium 2-ethylhexanoate as a hard, white solid (97% isolated yield). Anhydrous sodium 2-ethylhexanoate is very hygroscopic and was handled under an inert and substantially dry atmosphere.
Example 2
Commercially available CrCl3(THF)3 obtained from Aldrich contained significant amounts of water; therefore, further drying was used to provide anhydrous CrCl3(THF)3 as follows. A round bottom flask (50 mL) was charged with a stir bar, CrCl3(THF)3 (8 g) and THF (25 mL). Trimethylsilylchloride (8 mL) was added dropwise to the vigorously stirring solution. The mixture was allowed to stir overnight. The purple solid was collected by filtration, washed once with pentane (50 mL) and dried under dynamic vacuum to afford the product (93% yield). The anhydrous CrCl3(THF)3 was a fine, pink-purple powder, while the damp material is a darker purple, clumpy solid.
Example 3
A round bottom flask (1 L) was charged with CrCl3(THF)3 (21.01 g, 0.0561 mol), anhydrous sodium 2-ethylhexanoate (27.99 g, 0.168 mol) and THF (250 mL). The reaction was allowed to stir at 23° C. for 96 hr, and the solvent was removed to yield a green tar-like material. The solid was heated at 30° C. under vacuum for 2 hr then extracted into pentane (600 mL) and filtered through Celite® filter aid. The solution was very viscous making it difficult to filter. A large amount of green solid remained undissolved after filtration. The solvent was removed producing a green film (5.1 g). FIG. 7 provides an IR spectrum for the chromium(III) 2-ethylhexanoate produced using a sodium 2-ethyl hexanoate to CrCl3(THF)3 molar ratio of approximately 3. FIG. 8 provides an expanded section, 2000 cm−1 to 1000 cm−1, of the IR spectrum for the chromium(III) 2-ethylhexanoate produced using the sodium 2-ethyl hexanoate to CrCl3(THF)3 molar ratio of approximately 3. The infrared peak height and various infrared peak height ratios are provide in Table 1.
Example 4
A round bottom flask (500 mL) was charged with CrCl3(THF)3 (7.27 g, 0.0194 mol) and THF (100 mL). A solution of anhydrous sodium 2-ethylhexanoate (10.00 g, 0.0602 mol) in THF (60 mL) was added to the heterogeneous CrCl3(THF)3 solution while stirring. The reaction mixture was allowed to stir at 25° C. for 24 hr, after which time the solvent was removed to yield a green tacky solid. This green solid was then heated at 35° C. under vacuum for 2 hr, after which the product was extracted into cyclohexane (400 mL) and filtered through Celite® filter aid. The solvent was removed from the filtrate under vacuum producing a green tacky solid (7.1 g). FIG. 9 provides an IR spectrum for the chromium(III) 2-ethylhexanoate produced using the sodium 2-ethyl hexanoate to CrCl3(THF)3 molar ratio of approximately 3.1. FIG. 10 provides an expanded section, 2000 cm−1 to 1000 cm−1, of the IR spectrum for the chromium(III) 2-ethylhexanoate produced using the sodium 2-ethyl hexanoate to CrCl3(THF)3 molar ratio of approximately 3.1. The infrared peak height and various infrared peak height ratios are provide in Table 1.
Example 5
A round bottom flask (500 mL) was charged with CrCl3(THF)3 (20.10 g, 0.0537 mol). A solution of anhydrous sodium 2-ethylhexanoate (29.42 g, 0.177 mol) in THF (250 mL) was added to the solid CrCl3(THF)3 while stirring. The reaction mixture was allowed to stir at 23° C. for 72 hr, after which time the solvent was removed to yield a green tacky solid. This green solid was than heated at 30° C. under vacuum for 2 hr, after which the product was extracted into pentane (500 mL) and filtered through Celite®. The solvent was removed from the filtrate under vacuum producing a green tacky solid (24.5 g).

Example 6
Sodium Removal
Method A—
Me3SiCl method. A 20 mL vial was charged with the product of EXAMPLE 5 (0.373 g, approximately 0.68 mmol) and 10 mL of cyclohexane. The vial was then shaken vigorously to dissolve the chromium complex, resulting in a viscous solution. Me3SiCl (0.030 g, 0.28 mmol) was then added to the solution and a white precipitate formed immediately. The reaction mixture was allowed to stand overnight, over which time a green gel had formed that settled out, leaving behind a very light green solution.
Method B)—
2-Ethylhexanoic acid method. A 20 mL vial was charged with CrCl3(THF)3 (1.00 g, 2.67 mmol), sodium 2-ethylhexanoate (1.340 g, 8.06 mmol), 2-ethylhexanoic acid (0.116 g, 0.80 mmol) and THF (15 mL). The mixture was stirred for 3 days, over which time a red-violet solution and a white solid formed. The solvent was removed under vacuum and the product was extracted with cyclohexane, filtered through Celite® filter aid, and dried under vacuum to produce a blue-green oil. ICP-OES: Cr, 11.85 wt. %; Na, 0.02 wt. %.
FIG. 13 provides an IR spectrum for the sodium-free chromium(III) 2-ethylhexanoate produced using Method A on the chromium(III) 2-ethylhexanoate produced using the sodium 2-ethylhexanoate to CrCl3(THF)3 molar ratio of approximately 3.3 (EXAMPLE 5). FIG. 14 provides an expanded section, 2000 cm−1 to 1000 cm−1, of the IR spectrum for the sodium free chromium(III) 2-ethylhexanoate produced using the sodium 2-ethylhexanoate to CrCl3(THF)3 molar ratio of approximately 3.3 (EXAMPLE 5). The infrared peak height and various infrared peak height ratios are provide in Table 1.
Example 7
A round bottom flask (500 mL) was charged with CrCl3(THF)3 (19.00 g, 0.0507 mol). A solution of anhydrous sodium 2-ethylhexanoate (34.00 g, 0.205 mol) in THF (200 mL) was added to the solid CrCl3(THF)3 while stirring. This reaction mixture was allowed to stir at 23° C. for 60 hr, after which time the solvent was removed to yield a green foamy solid. This solid was heated at 30° C. under vacuum for 2 hr, then extracted into pentane (200 mL) and filtered through Celite® filter aid twice. The solvent was removed from the filtrate under vacuum to provide a green film (27.9 g). FIG. 15 provides an IR spectrum for this chromium(III) 2-ethylhexanoate produced using the sodium 2-ethylhexanoate to CrCl3(THF)3 molar ratio of approximately 4. FIG. 16 provides an expanded section, 2000 cm−1 to 1000 cm−1, of the IR spectrum for this chromium(III) 2-ethylhexanoate produced using the sodium 2-ethylhexanoate to CrCl3(THF)3 molar ratio of approximately 4. The infrared peak height and various infrared peak height ratios are provide in Table 1.
Infrared Analysis
Two commercially available chromium(III) 2-ethylhexanoate samples and the four chromium(III) 2-ethylhexanoate samples produced in Example 3-7 were analyzed using infrared analysis. The first commercially available chromium(III) 2-ethylhexanoate sample and the four chromium(III) 2-ethylhexanoate samples were prepared for IR analysis using the following procedure. In a drybox, 5 mg of the sample and 500 mg of anhydrous KBr were extensively ground together by mortar and pestle. A 10-mm KBr sample pellet was then formed by placing 100 mg of the extensively ground sample in a Spectra-Tech Econo-Press Kit. The sample was then transferred to the IR via an airtight receptacle. The IR spectrum was then acquired under a nitrogen purge. Background spectra using pure KBr pellets were collected prior to collecting the desired spectra.
The second commercially available chromium(III) 2-ethylhexanoate sample was manufactured using mineral spirits as the diluent. A couple of drops of the second commercially available chromium(III) 2-ethylhexanoate sample were then placed between two salt KBr plates and transferred to the IR via an airtight receptacle. The IR spectrum was then acquired under a nitrogen purge.
The IR spectra were obtained using a Nicolet® Magna-IR 560 Fourier Transform Infrared spectrometer with a Class 2, 1 mW HeNe laser source, KBr beamsplitter and DTGS detector. A typical experiment encompassed 64 scans (1-4 cm−1 resolution) with the background scans collected after the sample scans. The spectra were analyzed using OMNIC® 7.4 software from Thermo Fisher Scientific Inc.

High Energy X-Ray Diffraction Analysis

The first commercially available chromium(III) 2-ethylhexanoate composition, the chromium(III) 2-ethylhexanoate composition produced using the procedure of Example 5, and the chromium(III) 2-ethylhexanoate composition as produced according to R. T. Hart Jr., N. A. Eckert, J. K. Ngala, A. F. Polley, C. J. Benmore, A. Clark, S. Macha, Presentation CATL 20, The 237th ACS National Meeting, Salt Lake City, Utah, Mar. 23, 2009, (hereafter “the Hart chromium(III) 2-ethylhexanoate composition”) was analyzed using high energy X-ray diffraction. The high energy X-ray diffraction data was collected at station 11-ID-C of the Advanced Photon Source at Argonne National Laboratory using a monochromatic X-ray beam of 115 keV having an oval beam profile with a major axis of 15 μm and a minor axis of 1.5 of μm was used to illuminate a 3 mm thick sample approximately 1130 mm from the detector. In this particular instance, a sufficient amount of sample (0.1 mg to 100 mg) to provide a 3 mm path length was placed in a 5 mm 0 D Pyrex® tube having 1 mm thick walls. Once the sample was placed in the Pyrex® tube, the Pyrex® tube was then evacuated, backfilled with N2, and then flame sealed. The high energy X-ray diffraction pattern for the sample contained in the Pyrex® tube was then obtained by impinging the monochromatic X-ray beam of 115 keV (having an oval beam profile with a major axis of 15 μm and a minor axis of 1.5 of μm) upon the sample at a temperature of 298° K. The resulting diffraction pattern was collected on a MAR345 image plate (a 345 mm diameter image plate) at approximately 1130 millimeters from the sample. The angle between the X-ray beam source and the image plate was 180 degrees and a beamstop lined up with the center of the image plate between the sample and the image plate. Typically, the image plate is exposed for 0.5 seconds. Generally, the exposure time can be adjusted to obtain a balance between signal to noise ratio (longer exposure time provide improved signal to noise ratios) and image plate saturation (shorter exposure times reduced image plate detector saturation). Sample to detector distance, beam energy and detector orientation were determined using an external reference scan of CeO2 powder. Background diffractions of an identical empty Pyrex® tube and air were also collected on MAR345 image plates to provide environment and background corrections, respectively, for the sample analysis. High energy X-ray diffraction image manipulations and data analysis was performed using FIT2D (Hammersley, A. P.; Svensson, S. O.; Hanfland, M.; Fitch, A. N.; Häusermann, D. High Pressure Res. 1996, 14, 235-248) version 12.077 (Apr. 5, 2005—Internal Report (1998), ESRF98HA01T, FIT2D V9. 129 Reference Manual V3. 1; A. P. Hammersley) and PDFgetX2 (Qiu, X.; Thompson, J. W.; Billinge, S. J. L. J. Appl. Crystallogr. 2004, 37, 678).
The raw sample image (sample contained in a Pyrex® tube), environment image (empty Pyrex® tube), and background image (air) were corrected for alignment, orientation and sample to detector distance using Fit2D and were then converted to momentum space intensity histograms, I(Q), by radially summing the corrected data images (using standard corrections for multiple scattering, and X-ray polarization using PDFgetX2 (version 1) as shown in B Tomberli, C J Benmore, P A Egelstaff, J Neuefeind and V Honkimäki. 2000 J. Phys.: Condens. Matter, 12, 2597). The environment and the background momentum space intensity histograms were then subtracted from the raw sample momentum space intensity histogram within PDFgetX2 to provide a pure sample momentum space intensity histogram. The pure sample momentum space intensity histogram, I(Q), was then converted to a Structure function, S(Q) which was then converted to the pair distribution function, G(r), by the Fourier transformation of the Structure function,

(where Q=4π sin(θ)/λ, ρ(r) is the local density, and ρ0 is the average density) up to Qmax=25 Å−1 within PDFgetX2. The pair distribution function, G(r) was then normalized to provide the reduced pair distribution function, g(r) where g(r)=G(r)ρ0. The data points (r,g(r)) are referred to herein as the high energy X-Ray diffraction g(r) data points. Table 5 provides the high energy X-ray diffraction g(r) data points (from 1 angstrom to 6 angstroms) for a chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5, the Hart chromium(III) 2-ethylhexanoate composition, and the first commercially available chromium(III) 2-ethylhexanoate composition. FIG. 17 provides a plot of g(r) versus r (from 1 angstrom to 6 angstroms) for the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5 and the first commercially available chromium(III) 2-ethylhexanoate composition. FIG. 18 provides a plot of g(r) versus r (from 1 angstrom to 6 angstroms) for the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5 and the Hart chromium(III) 2-ethylhexanoate composition. It can be clearly seen that the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5 is significantly different from the first commercially available chromium(III) 2-ethylhexanoate composition and the Hart chromium(III) 2-ethylhexanoate composition.

A vacuum phase mononuclear chromium(III) acetate model was constructed heuristically based on the strong correlations in the experimental radial distribution function of the chromium(III) 2-ethyl hexanoate produced according to Example 5. The initial mononuclear chromium(III) acetate structure was built using a reasonable chromium-oxygen bond distance obtained from the high-energy X-ray diffraction of the chromium(III) 2-ethylhexanoate sample produced by the method in Example 5 and the carbon-oxygen, carbon-carbon, and carbon-hydrogen bond distances of the acetate anion published in Nature 205, 694-695 (13 Feb. 1965). It should be noted that all three high energy X-ray diffraction analyzed chromium(III) 2-ethylhexanoate compositions provide nearly the same chromium-oxygen bond distance (within 0.05 of an Angstrom). Consequently, without being limited to theory, it was believed that this was a good initial starting point for the chromium-oxygen bond distance on which to construct a gas phase mononuclear chromium(III) acetate model. The initial model was then optimized using SemiChemGaussView (version 3.0) by varying the chromium-oxygen bond distance and the oxygen-chromium-oxygen-carbon dihedral angle while imposing D3h symmetry on the 10 central atoms. Table 6 provides the atomic coordinates of the optimized chromium(III) acetate model obtained from SemiChemGaussView.

PDFFit as implemented in PDFgui was then used to then calculate the pair distribution functions of the optimized mononuclear chromium(III) model (Proffen, T.; Billinge, S. J. L. J. Appl. Crystallogr. 1999, 32, 572-575). Table 7 provides the calculated high energy X-ray diffraction d(r) data points for the optimized chromium(III) acetate model. It should be noted that the utilized procedure generates a radial distribution function, d(r), and it is the d(r) data points that are presented in Table 7. To compare the calculated high energy X-ray diffraction d(r) data of the optimized mononuclear chromium(III) acetate model to high energy X-ray diffraction g(r) data of a chromium carboxylate sample, the d(r) data points must to converted to g(r) data. The relationship between high energy X-ray diffraction d(r) data generated by PDFgui and high energy X-ray diffraction g(r) data points is g(r)=(d(r)/(4π*r*ρ0))+1.

The high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5, the Hart chromium(III) 2-ethylhexanoate composition, and the first commercially available chromium(III) 2-ethylhexanoate composition were compared to the calculated high energy X-ray diffraction data points of the mononuclear chromium(III) acetate model to determine how well these chromium(III) 2-ethylhexanoate compositions compared to a mononuclear chromium(III) 2-ethylhexanoate via a model of a mononuclear chromium(III) acetate. The comparisons were performed by separately optimizing the fit between each chromium(III) 2-ethylhexanoate composition and the chromium(III) acetate model over the desired range of r values and calculating the goodness of fit test value, R2, via the equation R2=1−(SSerr/SStot) for the same range of r as described herein.
Each optimization fit was performed by 1) converting the calculated high energy X-ray diffraction d(r)data points for the mononuclear chromium(III) acetate model to calculated high energy X-ray diffraction g(r)data points for the mononuclear chromium(III) acetate model and scaling the calculated high energy X-ray diffraction g(r)data points to the high energy X-ray diffraction data points of the chromium(III) 2-ethylhexanoate composition using the equation g(r)=((((d(r)/(4π*r*ρ0))+1)*fac)+C) and 2) minimizing the sum of the squared differences between the calculated high energy X-ray diffraction g(r) data points for the mononuclear chromium(III) acetate model and the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition using rho, fac, and C as scaling and optimization variables under the constraint that the scaled and optimized calculated high energy X-ray diffraction g(r) data point for the mononuclear chromium(III) acetate model g(r) data point at r=1.79 Angstroms is equal to 0. Within this procedure, g(r)=(d(r)/(4π*r*ρ0)) converts the radial distribution d(r) data points of the optimized mononuclear chromium(III) acetate model presented Table 6 to g(r) data points which can be compared to the high energy X-ray diffraction g(r) data points obtained by experiment for the tested chromium(III) 2-ethylhexanoate compositions, and fac and C are scaling factors to allow for an optimum fit between the calculated high energy X-ray diffraction data points of the mononuclear chromium(III) acetate model to the high energy X-ray diffraction data points of the chromium(III) 2-ethylhexanoate compositions. The optimization operations were performed using the Solver function within the Microsoft® Excel spreadsheet program but can be performed using other programs capable of solving for the minimum sum of squared differences using ρ0, fac, and C as variables in the scaling function under a constraint that the mononuclear chromium(III) acetate model g(r) data point (resulting from the scaling operation) at r=1.79 Angstroms equals 0.
The following procedure provides the steps utilized to create the Microsoft® Excel worksheet to optimize the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over an r value range of 1.3 to 4.0. Within a clean Microsoft® Excel worksheet:

    
    
        1. The values of r from 1.00 to 6.00 separated by the interval of 0.01 were placed into cells A10-A510 in ascending order.
        2. The corresponding values of d(r) for each r value of the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model from Table 7 were placed into cells B10-B510.
        3. The corresponding values of g(r) for each r value of the high energy X-ray diffraction g(r) data points of the chromium 2-ethylhexanoate sample of Example 5 were placed in cells C10-0510.
        4. A non-zero initial guess for ρ0, a non-zero initial guess for the optimization constant fac, and an initial guess for the optimization constant C were placed in cells D4, D5, and D6, respectively.
        5. The formula=((($B10/(4*PI( )*$A10*$D$4))+1)*$D$5)+$D$6 was placed into cell D10 and then referentially copied into cells D11-D510 (i.e. when referentially copied, the formula in D510 was =((($B510/(4*PI( )$A510*$D$4))+1)*$D$5)+$D$6).
        6. The formula=SUM(E10:E510) was placed into cell E8.
        7. The formula=(C40−D40)^2 was placed in cell E40 and referentially copied into cells E41-E310 (i.e., when referentially copied, the formula in E310 was =(C310−D310)^2) and ensuring that cells E10-E39 and E311-E510 were blank.
        8. The optimization between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model was then performed by:
        
            a. Opening the Solver routine in Microsoft® Excel;
            b. Inputting E8 the Solver routine box labeled “Set Target Cell”;
            c. Selecting the target cell to equal to a minimum value;
            d. Inputting cells D4, D5, and D6 ($D$4:$D$6) into the Solver routine box labeled “By Changing Cells”;
            e. Inputting the constraint that cell $D$89=0 into the Solver routine box labeled “Subject to the Constraints”;
            f. Clicking the solve box and then clicking the OK button if Solver routine successfully converged to a solution (while ensuring that the keep solution radio button was selected).

It should be noted that these steps created a worksheet that includes data points and utilize general formulas, relational formulas, and procedures that can allow the worksheet to be adapted to optimizing the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over other r values ranges.

        
        
    
    


When performing the procedure to optimize the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model and utilizing initial values of ρ0=0.1, fac=0.1, and C=0, the Solver routine converged to a solution having ρ0=0.0101, fac=0.1410, and C=0.1266 (rounded to four decimal places), and a minimized sum of the squared differences between the calculated high energy X-ray diffraction g(r) data points for the mononuclear chromium(III) acetate model and the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 equal to 136.5487 (rounded to four decimal places). It should be noted that there can be multiple converge solutions for the values of ρ0, fac, and C which can provide the same minimized sum of the squared differences between the calculated high energy X-ray diffraction g(r) data points for the mononuclear chromium(III) acetate model and the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition. Often the difference in the converged values of ρ0, fac, and C can be the selection of the initial values for ρ0, fac, and C. For example, a minimized sum of the squared differences between the calculated high energy X-ray diffraction g(r) data points for the mononuclear chromium(III) acetate model and the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 of 136.5487 (rounded to four decimal places) can be obtained utilizing initial values of ρ0=0.1, fac=0.1, and C=0.1 (which converge to provide values of to a solution having ρ0=0.0203, fac=0.2828, and C=−0152, rounded to four decimal places) or utilizing initial values of ρ0=0.2, fac=0.2, and C=0 (which converge to provide values of to a solution having ρ0=0.0230, fac=0.3207, and C=−0.0531, rounded to four decimal places). Consequently, the initial values of ρ0, fac, and C, and the converged values of ρ0, fac, and C are not particularly important as long as the true minimized sum of the squared differences between the calculated high energy X-ray diffraction g(r) data points for the mononuclear chromium(III) acetate model and the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition is obtained.
The goodness of fit test value was then calculated by applying the equation R2=1−(SSerr/SStot) where SSerr=Σr(int)r(fin)(comp g(r)−model g(r))2 and SStot=Σr(int)r(fin)(comp g(r)−mean of model g(r))2 where r(int) is the initial r value of g(r) over which the goodness of fit is to be calculates and r(fin) is the final r value of g(r) over which the goodness of fit is to be calculated. Generally, the goodness of fit test can be applied over the same range of r values as the optimization between the chromium(III) carboxylate composition and the chromium(III) acetate model. However, in some instances, it can be desirable to perform the goodness of fit test over a subset of the r values over which optimization between the chromium(III) carboxylate composition and the chromium(III) acetate model was performed.
The following procedure provides the steps utilized to extend the Microsoft® Excel worksheet utilized to optimize the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over an r value range of 1.3 to 4.0 to include the formulas to calculate the goodness of fit test value, R2, between the optimized fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over an r value range of 1.3 to 4.0. The procedure builds upon the Microsoft® Excel worksheet utilized to optimize the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over an r value range of 1.3 to 4.0. It should be noted the steps to create the worksheet include data points and utilize general formulas, relational formulas, and procedures to allow the worksheet to be easily adapted to calculate the goodness of fit between the optimized fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over other r values ranges.
Within the Microsoft® Excel worksheet that was created to optimize the fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over an r value range of 1.3 to 4.0:

    
    
        1. The formula=SUM(F10:F510) was place into cell F8.
        2. The number 1 into cells F40 to F310 (the cells corresponding the r value range over which the goodness of fit is to be calculated all other cells over the range of F10 to F510 are blank).
        3. The formula=SUM(G10:G510) was placed into cell G8.
        4. The formula=(C40−D40)^2 was placed into cell G40 and was then referentially copied into cells G41-G310 (i.e. when referentially copied, the formula in G310 was =(C310−D310)^2).
        5. The formula=SUM(H10:H510) was placed into cell H8.
        6. The formula=C130 was placed into cell H40 and was then referentially copied into cells H41-H310 (i.e. when referentially copied, the formula in H310 was =C310).
        7. The formula=SUM(I10:I510) was placed into cell I8.
        8. The formula=(H40−(H$8/F$8))^2 was placed into cell I40 and was then referentially copied into cells I41-I310 (i.e. when referentially copied, the formula in I310 was =(H310−(H$8/F$8))^2).
        9. The formula=1−(G8/I8) was placed into cell I4 and provides the goodness of fit test value.

It should be noted that these steps created a worksheet that includes data points and utilize general formulas, relational formulas, and procedures that would allow the worksheet to be adapted to calculating the goodness of fit test value between the optimized fit between the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition of Example 5 and the calculated high energy X-ray diffraction d(r) data points of the chromium(III) acetate model over other r values ranges by selecting the appropriate cell references and formulas.

    
    


Table 8 provides the goodness of fit test values for comparing the high energy X-ray diffraction g(r) data points of the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5, the high energy X-ray diffraction of the first commercially available chromium(III) 2-ethylhexanoate composition, and the Hart chromium(III) 2-ethylhexanoate composition to a calculated high energy X-ray diffraction g(r) points of a mononuclear chromium(III) acetate model for various ranges of r. In each instance, the optimization was performed between the indicated chromium(III) 2-ethylhexanoate and the calculated and high energy X-ray diffraction d(r) points of the mononuclear chromium(III) acetate model in Table 7 over the identical r value range as the r values for the goodness of fit test values. FIGS. 18, 19, and 20, provide plots comparing the high energy X-ray diffraction g(r) data of the chromium(III) 2-ethylhexanoate composition prepare according to the procedure of Example 5, the first commercially available chromium(III) 2-ethylhexanoate composition, and an aqueous metathesis produced sample of chromium(III) acetate to the calculated high energy X-ray diffraction g(r) data of the mononuclear chromium(III) acetate model (optimized over the r value range of 1.3 to 4.0 Angstroms) described herein. The goodness of fit test values and FIGS. 18, 19, and 20 show that the chromium(III) 2-ethylhexanoate composition prepared according to the procedure of Example 5 more closely resembles a mononuclear chromium(III) carboxylate (via comparison to a mononuclear chromium(III) acetate model) than the first commercially available chromium(III) 2-ethylhexanoate composition and the aqueous metathesis produced sample of chromium(III) acetate.
