TECHNICAL FIELD
This invention relates to compositions comprising alkene benzenes, compositions comprising alkene benzene sulfonates, methods for making alkene benzenes, methods for making alkene benzene sulfonates, compositions comprising alkylbenzenes, compositions comprising alkylbenzene sulfonates, methods for making alkylbenzenes, and methods for making alkylbenzene sulfonates. This invention relates to compositions comprising substituted alkene benzenes, compositions comprising substituted alkene benzene sulfonates, methods for making substituted alkene benzenes, methods for making substituted alkene benzene sulfonates, compositions comprising substituted alkylbenzenes, compositions comprising substituted alkylbenzene sulfonates, methods for making substituted alkylbenzenes, and methods for making substituted alkylbenzene sulfonates, where the benzene ring is substituted with one or more groups designated R*, where R* is defined herein. This invention describes a process to produce 2-phenyl linear alkyl benzene sulfonates (2-PhLAS) by cross metathesis of alpha-methyl styrene (AMS) or 3-phenyl-1-butene (3Ph1C4) with a linear alpha olefin (AO) or a linear internal olefin (IO) to produce 2-phenyl linear alkene benzenes (2-PhLAeB). The 2-phenyl linear alkene benzenes (2-PhLAeB) are hydrogenated and sulfonated by well-known methodologies to yield 2-phenyl linear alkylbenzene sulfonates (2-PhLAS). This invention describes a process to produce substituted 2-phenyl linear alkyl benzene sulfonates (2-Ph*LAS), where the benzene ring is substituted with one or more groups designated R*, by cross metathesis of substituted alpha-methyl styrene (AM*S), where the benzene ring is substituted with one or more groups designated R*, or substituted 3-phenyl-1-butene (3Ph*1C4) where the benzene ring is substituted with one or more groups designated R*, with a linear alpha olefin (AO) or a linear internal olefin (IO) to produce substituted 2-phenyl linear alkene benzenes (2-Ph*LAeB), where the benzene ring is substituted with one or more groups designated R*, where R* is defined herein. The substituted 2-phenyl linear alkene benzenes (2-Ph*LAeB) are hydrogenated and sulfonated by well-known methodologies to yield substituted 2-phenyl linear alkylbenzene sulfonates (2-Ph*LAS). 2-Phenyl linear alkylbenzene sulfonates (2-PhLAS) and substituted 2-phenyl linear alkylbenzene sulfonates (2-Ph*LAS) are high-efficiency surfactants useful in hand soaps, dish soaps, hard surface cleaners, laundry detergents, and in cleaning supplies.
In addition, this invention relates to compositions comprising 2-ethoxylated hydroxymethylphenyl linear alkyl benzenes and to compositions comprising 2-propoxylated hydroxymethylphenyl linear alkyl benzenes. This invention also relates to methods of making 2-ethoxylated hydroxymethylphenyl linear alkyl benzenes and to methods of making 2-propoxylated hydroxymethylphenyl linear alkyl benzenes. This invention also relates to the use of compositions comprising 2-ethoxylated hydroxymethylphenyl linear alkyl benzenes and to the use of compositions comprising 2-propoxylated hydroxymethylphenyl linear alkyl benzenes. In addition, this invention relates to articles of manufacture comprising compositions comprising 2-ethoxylated hydroxymethylphenyl linear alkyl benzenes and to articles of manufacture comprising compositions comprising 2-propoxylated hydroxymethylphenyl linear alkyl benzenes. 2-ethoxylated hydroxymethylphenyl linear alkyl benzenes and 2-propoxylated hydroxymethylphenyl linear alkyl benzenes are surfactants, more specifically non-ionic surfactants, useful in hand soaps, dish soaps, hard surface cleaners, laundry detergents, and in various cleaning supplies and detergents and detergent compositions.
BACKGROUND
Global demand for linear alkylbenzene sulfonates (LAS) is 6.7 billion lb/yr (“The Future of LAB” Amandeep Singh, Inform Magazine AOCS, March 2012) with 2.7% demand growth. Alkylbenzene sulfonates, especially those made from linear alkylbenzenes (LAB), are primary surfactants used in household cleaners and detergents. The demand for linear alkyl benzene sulfonates continues to grow because of their low cost, strong performance, and biodegradability.
A limitation to increased use of LAS surfactants and related linear surfactants has been because they have poor solubility in cold water and hard water conditions (US 2012/0213726 and WO 2012/138423). This is supported by J. Scheibel in Journal of Surfactants and Detergents, (2004) 7, 319, which reported the 4-, 5-, and 6-PhLAS isomers are sensitive to calcium, which form aggregates and are less surface active than the 2-PhLAS and 3-PhLAS isomers. Also J. Scheibel reported that the 2-PhLAS surface activity (critical micelle concentration (CMC)) was 600 ppm while 3-PhLAS CMC was 700 ppm, under the same conditions. Therefore, it takes 15% less of the 2-PhLAS isomer to form a micelle compared to the 3-PhLAS isomer. This aligns well with the publicly communicated “green” initiatives of major detergent companies such as Proctor & Gamble, which by 2020 seeks a 20% reduction in packaging compared to 2010 levels, and a 20% reduction in truck transportation compared to 2010 levels (http://www.pg.com/en_US/sustainability/environmental_sustainability/environmental_vision.shtml; as accessed on Apr. 9, 2013).
One of the “holy grails” of the detergent industry is more concentrated cleaning power. Many industrial experts have described the superior cleaning performance of the 2-PhLAS isomer over the other LAS isomers (e.g., the 1-, 3-, 4-, 5- and 6-PhLAS). U.S. Pat. No. 6,887,839 describes high 2-PhLAS mixtures are more effective cleaning agents over their counterparts with lower 2-PhLAS isomeric content, this is attributed to an unexpected increase in tolerance of water hardness minerals usually associated with precipitation of the active detergent agent. Further fine-tuning of cleaning performance of 2-PhLAS-based agents may be achieved by substitution of additional functional groups on the aromatic ring. For example, 2-tolyl linear alkylbenzene sulfonates have been reported to have lower Krafft temperatures and superior hard water tolerance compared to commercial linear alkylbenzene sulfonate materials (U.S. Pat. No. 6,995,127).
There are two currently used commercial production processes for LAS. The first, the HF alkylation of detergent (C10-C13) olefins, gives 18% of the 2-PhLAB isomer while the second, the DetalTM process (licensed by UOP), uses a zeolite catalyst to alkylate detergent olefins and produces 25-35% of 2-PhLAB (Zoller, U. “Handbook of Detergents: Part F Production,” v. 142, CRC Press, Boca Raton, Fla., 2009, p 111). It is estimated that  ̃80% of current manufacturers use the HF process, but new capacity is typically based upon the DetalTM process which also enjoys lower capital costs. It is important to point out that both the HF and DetalTM processes have little control over the formation of the 2-PhLAB isomer as these processes are Friedel-Craft type alkylation of the aromatic ring with an olefin. Under these conditions the double bond of the olefin is isomerized (i.e., migrated along its backbone) resulting in positional-isomeric mixtures of PhLAB. (e.g., 1-PhLAB, 2-PhLAB, 3-PhLAB, 4-PhLAB, 5-PhLAB, 6-PhLAB, etc.).
Over the years efforts have been made to increase the concentration of 2-PhLAS isomer content over other LAS isomers. For example, U.S. Pat. No. 6,562,776 describes a mixture of salts of alkylbenzene sulfonates, prepared by the HF process, wherein the 2-phenyl isomer content of such alkylbenzene sulfonate salts is 42%-82% by weight based on the total weight of LAS isomers.
U.S. Pat. No. 6,887,839 is incorporated by reference and describes high content 2-phenyl linear alkyl benzene sulfonates having enhanced hard water tolerance. This patent does not produce 2-phenyl linear alkylbenzene sulfonates in >85% isomeric purity and does not describe olefin metathesis to produce 2-phenyl linear alkylbenzene sulfonates.
U.S. Pat. App. Pub. No 2012/0213726 is incorporated by reference and describes bio-based linear alkyl phenyl sulfonates (linear alkylbenzene sulfonates) incorporating C10-C14 olefins which at least 50% bio-based. The bio-based C10-C14 olefins may be produced by metathesis of seed oils as described in U.S. Pat. App. Pub. No US2010/0145086. U.S. Pat. App. Pub. No. 2012/0213726 does not describe olefin metathesis of alpha-methyl styrene or 3-phenyl-1-butene to produce linear alkyl phenyl sulfonates (linear alkylbenzene sulfonates).
WO Pat. App. Pub. No. 2012/138423 is incorporated by reference and describes C10-C13 linear alkyl phenyl sulfonates (linear alkylbenzene sulfonates) having a particular alkyl group distribution. This application describes using a particular C10-C13 olefin distribution to produce C10-C13 linear alkyl phenyl sulfonates (linear alkylbenzene sulfonates). It does not describe olefin metathesis of alpha-methyl styrene or 3-phenyl-1-butene to produce linear alkyl phenyl sulfonates (linear alkylbenzene sulfonates).
U.S. Pat. App. Pub. No. 2010/0145086 is incorporated by reference and is the seminal patent application describing the production of alpha olefins from alkenolysis of seed oils. It does not describe olefin metathesis of alpha-methyl styrene or 3-phenyl-1-butene to produce linear alkyl benzenes, linear 2-phenylalkylbenzenes, linear alkyl phenyl sulfonates, or linear alkylbenzene sulfonates.
U.S. Pat. No. 6,995,127 is incorporated by reference and describes relatively high content 2-tolyl linear alkyl benzene sulfonates having enhanced hard water tolerance. This patent does not produce 2-phenyl linear alkylbenzene sulfonates in >85% isomeric purity and does not describe olefin metathesis to produce 2-phenyl linear alkylbenzene sulfonates. Under the HF and DetalTM processes utilized, the resulting 2-tolyl linear alkyl benzene sulfonates predominantly comprise para-tolyl groups due to the ortho/para directing effects of methyl (alkyl) groups (combined with steric effects which disfavor ortho-substitution). Similarly, electron-withdrawing groups (i.e., NO2, CN, etc.) would yield predominantly meta-substituted isomers. In contrast, the methods described herein would allow for controlled substitution at any particular position of the aromatic ring or any desired combination of these positions. For example, commercially available tolylstyrenes are available as a mixture of approximately 60% meta- and 40% para-methyl substitution, which will produce a 2-tolyl linear alkylbenzene sulfonate with the same 60% meta- and 40% para-methyl substitution, or in a nearly pure para-methyl form.
Therefore, despite advances achieved in the art, a continuing need exists for further improvement in a number of areas, including methods for the production of alkylbenzenes and alkylbenzene sulfonates having improved selectivity of 2-phenyl linear alkylbenzene isomer production as well as compositions comprising improved 2-phenyl linear alkylbenzene isomer content. In addition, despite advances achieved in the art, a continuing need exists for further improvement in a number of areas, including methods for the production of substituted alkylbenzenes and substituted alkylbenzene sulfonates having improved selectivity of substituted 2-phenyl linear alkylbenzene isomer production as well as compositions comprising improved substituted 2-phenyl linear alkylbenzene isomer content, where the benzene ring is substituted with one or more groups designated R*, where R* is defined herein.
In addition, another particular problem is the need for surfactants which possess good solubility and/or foaming ability in hard water at cold temperatures. Therefore, it is desirable that a surfactant, particularly a surfactant for use as a detergent, have good solubility and/or good foaming ability in cold-hard water.
Hard water is defined as water that contains mineral salts (e.g., calcium and magnesium ions), where the mineral salts act to limit the ability a surfactant to produce foam or lather. Surfactants that have reduced foaming ability generally possess less cleaning power or detergency. In other words, surfactants that do not foam or lather are generally poor detergents.
Ionic surfactants are surfactants that possess ionic groups (e.g., sulfate groups). Unfortunately, ionic surfactants generally possess less foaming ability in hard water due to interactions with the mineral salts present in the hard water. Unlike ionic surfactants, non-ionic surfactants are surfactants that do not have ionic groups. Non-ionic surfactants as a result, generally do not react with nor are they affected by the mineral salts present in hard water. However, few non-ionic surfactants which possess good solubility and/or good foaming ability in cold-hard water are known and even fewer are commercially available. Therefore, an ongoing need exists for non-ionic surfactants which possess good solubility and/or good foaming ability in cold-hard water. Moreover, due to the differences in water sources, and the fact that detergent compositions are typically complex mixtures there is a need for a wide variety of surfactants (non-ionic and/or ionic) having various structures and properties.

In the molecular structures herein, the use of bold and dashed lines to denote particular conformation of groups follows the IUPAC convention. A bond indicated by a broken line indicates that the group in question is below the general plane of the molecule as drawn, and a bond indicated by a bold line indicates that the group at the position in question is above the general plane of the molecule as drawn. If an olefinic structure is depicted which could potentially exist in either cis (Z) or trans (E) configuration, the use of a wavy line in the depiction indicates that the configuration may be either cis or trans or a combination of the two:




Functional groups may be protected as necessary and any of the protecting groups commonly used in the art may be employed. Acceptable protecting groups may be found, for example, in Greene et al., Protective Groups in Organic Synthesis, 3rd Ed. (New York: Wiley, 1999).
A leaving group is a molecular fragment that departs with a pair of electrons in heterolytic bond cleavage. Leaving groups can be anions or neutral molecules. Examples of common anionic leaving groups are halides such as chloride (Cl−), bromide (Br−), and iodide (I−), and sulfonate esters, such as tosylate (TsO−). Examples of common neutral molecule leaving groups are water and ammonia.
2-Phenyl Linear AlkylBenzene Sulfonates
The present invention provides a method of making 2-phenyl linear alkylbenzene sulfonates. More particularly, herein is described a method of making 2-phenyl linear alkene benzenes by cross metathesis of at least one cross metathesis substrate with at least one olefinic substrate in the presence of at least one olefin metathesis catalyst, where the at least one cross metathesis substrate is selected from alpha-methyl styrene, substituted alpha-methyl styrene, sulfonated alpha-methyl styrene (AMS), sulfonated substituted alpha-methyl styrene, 3-phenyl-1-butene (3Ph1C4), substituted 3-phenyl-1-butene, sulfonated 3-phenyl-1-butene, and sulfonated substituted 3-phenyl-1-butene, where the at least one olefinic substrate is selected from at least one linear alpha olefin, at least one linear internal olefin, or a combination thereof. The 2-phenyl linear alkene benzene (2-PhLAeB or 2-Ph*LAeB) product is hydrogenated to yield 2-phenyl alkylbenzene. The 2-phenyl linear alkylbenzene product is sulfonated to yield high isomeric purity 2-phenyl linear alkylbenzene sulfonate (2-PhLAS or 2-Ph*LAS), where the isomeric purity is at least 85% by weight based on the total weight of linear alkyl benzene sulfonate isomers. Scheme 1 below shows a general synthesis of 2-phenyl linear alkyl benzene sulfonates using cross metathesis.

Olefinic Substrates
Olefinic substrates for use with the present invention include internal olefins, alpha olefins, and combinations thereof. Preferred, olefinic substrates for use with the present invention include linear internal olefins, linear alpha olefins, and combinations thereof.
The term “internal olefin” as used herein means an olefin wherein each of the olefinic carbons is substituted by at least one non-hydrogen substituent. The non-hydrogen substituents are selected from hydrocarbyl, and substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, and functional groups. The internal olefin is therefore at least disubstituted, and may further include additional non-hydrogen substituents such that the internal olefin is tri- or tetra-substituted. Each of the substituents on the internal olefinic carbons may be further substituted as described herein. The internal olefin may be in the Z- or E-configuration.
The internal olefin may be a single compound or a mixture of compounds. The internal olefin may comprise a single internal olefin or a plurality of internal olefins. A mixture of internal olefins may be used. The internal olefin may be hydrophobic or hydrophilic, although in a preferred embodiment, the internal olefin is hydrophobic.
For example, the internal olefin may be represented by the formula (RI)(RII)C═C(RIII)(RIV), wherein RI, RII, RIII, and RIV are independently selected from H, hydrocarbyl, and substituted hydrocarbyl, provided that at least one of RI and RII and at least one of RIII and RIV is other than H. In a preferred embodiment, either RI or RII and either RIII or RIV is H, such that the internal olefin is di-substituted.
Examples of internal di-substituted olefins may be represented by the formula (RI)(RII)C═C(RIII)(RIV), wherein RI, RII, RIII, and RIV are independently selected from H, 2-C4 to 20-C40, and substituted 2-C4 to 20-C40, provided that at least one of RI and RII and at least one of RIII and RIV is other than H.

In other words, for example, if RI and RIII are both H, then RII and RIV may be C2-C19 alkyl, where the carbon atoms in the alkyl chain may have only hydrogen atoms or a methyl group bonded to them. The term “linear internal olefin” as used herein also means any internal tri-substituted olefin represented by the formula (RI)(RII)C═C(RIII)(RIV), where RI and RIII are either H or methyl, but not both H and not both methyl, RII and RV may be independently C2-C19 alkyl, where the carbon atoms of the alkyl chain may have only hydrogen atoms or a methyl group bonded to them. The term “linear internal olefin” as used herein also means an internal tetra-substituted olefin represented by the formula (RI)(RII)C═C(RIII)(RIV), where RI and RIII are both methyl and RII and RIV may be independently C2-C19 alkyl, where the carbon atoms of the alkyl chain may have only hydrogen atoms or a methyl group bonded to them. The linear internal olefin may be in the Z- or E-configuration.

It will be appreciated by those of skill in the art that the methods described herein are not limited to making 2-phenyl linear alkene benzenes, 2-phenyl linear alkene benzene sulfonates, 2-phenyl linear alkylbenzenes, 2-phenyl linear alkyl benzene sulfonates, substituted 2-phenyl linear alkene benzenes, substituted 2-phenyl linear alkene benzene sulfonates, substituted 2-phenyl linear alkylbenzenes, and substituted 2-phenyl linear alkyl benzene sulfonates. Other alkene benzenes, alkylbenzenes, alkene benzene sulfonates, and alkyl benzene sulfonates may also be prepared by the methods described herein including without limitation alkene benzenes, functionalized alkene benzenes, branched alkene benzenes, substituted and non-substituted alkene benzenes, alkene benzene sulfonates, functionalized alkene benzene sulfonates, branched alkene benzene sulfonates, substituted and non-substituted alkene benzene sulfonates, alkylbenzenes, functionalized alkyl benzenes, branched alkylbenzenes, substituted and non-substituted alkylbenzenes, linear alkylbenzenes, functionalized linear alkyl benzenes, branched alkylbenzenes, substituted and non-substituted linear alkylbenzenes, functionalized alkyl benzene sulfonates, branched alkylbenzene sulfonates, substituted and non-substituted alkylbenzene sulfonates, linear alkylbenzene sulfonates, functionalized linear alkylbenzene sulfonates linear alkylbenzene sulfonates, substituted and non-substituted linear alkylbenzene sulfonates.
It will be appreciated by those of skill in the art that the use of olefinic substrates containing, for example, long alkyl substituents enables liquid-phase, room temperature (or greater) reactions and/or the use of reactors working at near atmospheric or slightly higher pressures.
In some preferred embodiments, the cross metathesis substrate is soluble in the olefinic substrate. The cross metathesis substrate may have a solubility of at least 0.25 M, at least 1 M, at least 3 M, or at least 5 M in the olefinic substrate. The cross metathesis substrate and the olefinic substrate may also be miscible at all concentrations.
As another example, the cross metathesis substrate has a low solubility in the olefinic substrate, and the cross metathesis reaction occurs as an interfacial reaction. It should be noted that, when one or more of the reactants is solid or gaseous, the reactions may still be carried out in the liquid phase by dissolving any solid or gaseous reactants in the liquid reactants, or by employing a solvent, as described herein.
The olefinic substrate and/or cross metathesis substrate may be provided in the form of a gas. Typically, the pressure of a gaseous cross-metathesis partner over the reaction solution is maintained in a range that has a minimum of about 10 psig, 15 psig, 50 psig, or 80 psig, and a maximum of about 250 psig, 200 psig, 150 psig, or 130 psig. Embodiments wherein the reaction pressures are lowered till near atmospheric pressure and in particular till pressures slightly above atmospheric allow for a reduction in equipment costs compared to embodiments performed at high pressure (e.g., pressures greater than 250 psi).
The olefin metathesis reactions (e.g., cross metathesis) of the disclosure are catalyzed by any of the metathesis catalysts that are described herein. The catalyst is typically added to the reaction medium as a solid, but may also be added as a solution wherein the catalyst is dissolved in an appropriate solvent. It will be appreciated that the amount of catalyst that is used (i.e., the “catalyst loading”) in the reaction is dependent upon a variety of factors such as the identity of the reactants and the reaction conditions that are employed. It is therefore understood that catalyst loading may be optimally and independently chosen for each reaction. In general, however, the catalyst will be present in an amount that ranges from a low of about 0.1 ppm, 1 ppm, or 5 ppm, to a high of about 10 ppm, 15 ppm, 25 ppm, 50 ppm, 100 ppm, 200 ppm, 500 ppm, or 1000 ppm relative to the amount of the olefinic substrate. Catalyst loading, when measured in ppm relative to the amount of the olefinic substrate, is calculated using the equation

Thus, the catalyst will generally be present in an amount that ranges from a low of about 0.00001 mol %, 0.0001 mol %, or 0.0005 mol %, to a high of about 0.001 mol %, 0.0015 mol %, 0.0025 mol %, 0.005 mol %, 0.01 mol %, 0.02 mol %, 0.05 mol %, or 0.1 mol % relative to the olefinic substrate.
In a preferred embodiment, the reactions of the disclosure are carried out under a dry, inert atmosphere. Such an atmosphere may be created using any inert gas, including such gases as nitrogen and argon. The use of an inert atmosphere is optimal in terms of promoting catalyst activity, and reactions performed under an inert atmosphere typically are performed with relatively low catalyst loading. The reactions of the disclosure may also be carried out in an oxygen-containing and/or a water-containing atmosphere, and in one embodiment, the reactions are carried out under ambient conditions. The presence of oxygen, water, or other impurities in the reaction may, however, necessitate the use of higher catalyst loadings as compared with reactions performed under an inert atmosphere.
In another preferred embodiment, the reactions of this invention can be run as to be completely atom efficient. For example, in the alpha olefin self-metathesis reaction to yield an internal olefin, the ethylene generated can be used in the hydrovinylation reaction to yield 3-phenyl-1-butene. Internal olefin cross metathesis with 3-phenyl-1-butene will yield 2-PhLAeB and an alpha olefin or ethylene. The alpha olefin is recycled back into the internal olefin reaction, as shown in Scheme 17. One skilled in the art can appreciate that in each step by-products may be form which can be recycled at the appropriate step, i.e., in III. Cross Metathesis Reaction, two 2-PhLAeB and ethylene may be formed; the ethylene is used in II. Hydrovinylation Reaction. The net result is no wasted carbon atoms in this invention.

Olefin Metathesis Catalyst
This invention is useful for the synthesis of high purity 2-PhLAB and high purity 2-Ph*LAB by any suitable olefin metathesis catalyst. Such metathesis reactions are not specifically limited, and include cross metathesis (CM), self-metathesis, ethenolysis, alkenolysis, and combinations thereof.
An Olefin metathesis catalyst according to the invention, is preferably a Group 8 transition metal complex having the structure of formula (I)

        n is 0 or 1, such that L3 may or may not be present;
        m is 0, 1, or 2;

Suitable supports for any of the catalysts described herein may be of synthetic, semi-synthetic, or naturally occurring materials, which may be organic or inorganic, e.g., polymeric, ceramic, or metallic. Attachment to the support will generally, although not necessarily, be covalent, and the covalent linkage may be direct or indirect. Indirect covalent linkages are typically, though not necessarily, through a functional group on a support surface. Ionic attachments are also suitable, including combinations of one or more anionic groups on the metal complexes coupled with supports containing cationic groups, or combinations of one or more cationic groups on the metal complexes coupled with supports containing anionic groups.
When utilized, suitable supports may be selected from silicas, silicates, aluminas, aluminum oxides, silica-aluminas, aluminosilicates, zeolites, titanias, titanium dioxide, magnetite, magnesium oxides, boron oxides, clays, zirconias, zirconium dioxide, carbon, polymers, cellulose, cellulosic polymers amylose, amylosic polymers, or a combination thereof. The support preferably comprises silica, a silicate, or a combination thereof.
In certain embodiments, it is also possible to use a support that has been treated to include functional groups, inert moieties, and/or excess ligands. Any of the functional groups described herein are suitable for incorporation on the support, and may be generally accomplished through techniques known in the art. Inert moieties may also be incorporated on the support to generally reduce the available attachment sites on the support, e.g., in order to control the placement, or amount, of a complex linked to the support.
The metathesis catalysts that are described herein may be utilized in olefin metathesis reactions according to techniques known in the art. The catalyst is typically added as a solid, a solution, or as a suspension. When the catalyst is added as a suspension, the catalyst is suspended in a dispersing carrier such as mineral oil, paraffin oil, soybean oil, tri-isopropylbenzene, or any hydrophobic liquid which has a sufficiently high viscosity so as to permit effective dispersion of the catalyst, and which is sufficiently inert and which has a sufficiently high boiling point so that is does not act as a low-boiling impurity in the olefin metathesis reaction. It will be appreciated that the amount of catalyst that is used (i.e., the “catalyst loading”) in the reaction is dependent upon a variety of factors such as the identity of the reactants and the reaction conditions that are employed. It is therefore understood that catalyst loading may be optimally and independently chosen for each reaction. In general, however, the catalyst will be present in an amount that ranges from a low of about 0.1 ppm, 1 ppm, or 5 ppm, to a high of about 10 ppm, 15 ppm, 25 ppm, 50 ppm, 100 ppm, 200 ppm, 500 ppm, or 1000 ppm relative to the amount of an olefinic substrate.
The catalyst will generally be present in an amount that ranges from a low of about 0.00001 mol %, 0.0001 mol %, or 0.0005 mol %, to a high of about 0.001 mol %, 0.0015 mol %, 0.0025 mol %, 0.005 mol %, 0.01 mol %, 0.02 mol %, 0.05 mol %, or 0.1 mol % relative to the olefinic substrate.
Other olefin metathesis catalysts suitable for use with the present invention include well-defined molybdenum and tungsten catalysts such as those developed by Schrock(Schrock, R. R. Chem. Rev. 2009, 109, 3211; Hartford, B. Chemical & Engineering News, “Z-Selective Metathesis of Macrocycles,” Volume 89, Issue 45, Nov. 7, 2011, page 11; Yu, M.; Wang, C.; Kyle, A. F.; Jakubec, P.; Dixon, D. J.; Schrock, R. R.; Hoveyda, A. H. Nature, Nov. 3, 2011, 479, 88); each of which is incorporated by reference, examples are shown in Scheme 11.

Polymer Sci., A, Polymer Chem. 1993, 31, 3151; and a review by Grubbs R. H., Chang S. Tetrahedron, 1998, 54, 4413-4450], which are incorporated by reference. A few years later, chemists at Goodyear reported a catalyst system composed of a cocktail of WCl6, ethanol and EtAlCl2 that interconverted olefin feedstocks [Calderon, N.; Chen, H. Y.; Scott, K. W. Tetrahedron Lett., 1967, 3327-3329], which is incorporated by reference. These early transition metal systems had limitations with respect to polar functional groups or impurities within the substrate feed; however, the initial discovery by Phillips Petroleum ultimately led to the development of the Phillips Triolefin Process which converted propylene into a mixture of ethylene and 2-butene using a silica-supported WO3 catalyst. This heterogeneous catalyzed process was first performed on an industrial scale in 1985 by Lyondell [Mol, J. C. Catalysis Today 1999, 51, 289-299; Mol, J. C. J. Mol. Catal. A: Chem. 2004, 213, 39-45] and today Lummus Technology provides the support for the process, known as OCT® (Olefins Conversion Technology) which currently produces over 1.5 billion pounds of propylene per year [Wittcoff, H.; Reuben, B. G.; Plotkin, J. S. Industrial organic chemicals, 2nd ed.; Wiley-Interscience, 2004; Mol, J. C. J. Mol. Catal. A: Chem. 2004, 213, 39-45], all of which are incorporated by reference.

Experimental Reactions
Reaction 1. Synthesis of 3-phenyl-1-butene by hydrovinylation of styrene




Under a stream of argon, (PPh3)2CoCl2 (15.0 g, 22.9 mmol), dichloromethane (3.0 L), and styrene (4.0 L, 34.4 mol) were combined in an 18 L Parr reactor. The reactor was sealed, and cooled to −10° C. while the headspace was purged with ethylene. A solution of diethylaluminum chloride in hexanes (1.0 M, 115 mL, 115 mmol) was introduced. The reactor was promptly sealed and charged with ethylene (435 psi).
After 14 h the pressure was released the reaction passed through a plug of silica gel. The silica gel was washed with dichloromethane and the organic fractions were combined and concentrated under rotary evaporation. Subsequent purification by vacuum distillation afforded 3-phenyl-1-butene (Bpt 45.7° C. to 46.0° C. at 5 mmHg, 4.1 kg, 89% yield and 99% purity). 3-Phenyl-1-butene was produced in >99% isomeric purity (neither 2-phenyl-2-butene nor 2-phenyl-1-butene isomers were detected by 1H NMR and <0.5% 2-phenyl-2-butene was detected by GC analysis). 1H NMR (400 MHz, CDCl3) δ 1.66 (d, J=6.8 Hz, 3H), 3.75 (m, 1H), 5.34 (ddd, J=10.4, 1.6 and 1.6 Hz, 1H), 5.36 (ddd, J=17.2, 1.6 and 1.6 Hz, 1H), 6.31 (ddd, J=17.2, 10.4 and 6.4 Hz, 1H), 7.28-7.46 (m, 5H); 13C NMR (101 MHz, CDCl3) 20.7, 43.2, 113.0, 126.1, 127.2, 128.4, 143.2, 145.4.
Reaction 2. Preparation of 2-Phenyl-3-decene




A 5 liter jacketed flask equipped with a reflux condenser and magnetic stir bar was charged with 1-octene (1.70 kg, 15.1 mol) and 3-phenyl-1-butene (0.50 kg, 3.78 mol). The reaction mixture was sparged with argon for 45 minutes and heated to 45° C. Grubbs metathesis catalyst C827 (0.313 g, 0.378 mmol) in dichloromethane (3.0 mL) was subsequently added to the reaction mixture. The reaction mixture was allowed to stir at 45° C. under a slow, continuous argon purge for 6 hours. The reaction mixture was then cooled to room temperature and filtered through a plug of silica gel. The filter cake was washed with hexanes twice and all organic fractions combined and concentrated under reduced pressure. Subsequent purification by vacuum distillation afforded 2-phenyl-3-decene (Bpt 87.9° C. at 50 mmHg, 488 g, 56.1% yield, 99% purity). GC analysis determined the product to be a mixture of cis-2-phenyl-3-decene (8.3%) and trans-2-phenyl-3-decene (91.7%). 1H NMR (400 MHz, CDCl3) δ 0.96 (t, J=7.2 Hz, 3H), 1.25-1.60 (m, 11H), 2.09 (pquar, J=7.2 Hz, 2H), 3.49 (pquint, J=7.0 Hz, 1H), 5.50-5.57 (m, 1H), 5.60-5.70 (m, 1H), 7.21-7.30 (m, 3H), 7.34-7.38 (m, 2H). 13C NMR (101 MHz, CDCl3) δ 15.7, 23.0, 24.0, 30.1, 30.7, 32.9, 33.7, 43.1, 124.6, 125.8, 127.0, 127.9, 133.4, 144.7.
Reaction 3. Preparation of 2-Phenyl-3-undecene




A 5 liter jacketed flask equipped with a reflux condenser and magnetic stir bar was charged with 1-nonene (330 g, 2.61 mol) and 3-phenyl-1-butene (1.04 kg, 7.84 mol). The reaction mixture was sparged with argon for 45 minutes and heated to 45° C. Grubbs metathesis catalyst C827 (0.216 g, 0.261 mmol) in dichloromethane (3.0 mL) was subsequently added to the reaction mixture. The reaction mixture was allowed to stir at 45° C. with slow, continuous argon purge for 6 hours. The reaction mixture was then cooled to room temperature and filtered through a plug of silica gel. The filter cake was washed with hexanes twice and all organic fractions combined. Subsequent purification by vacuum distillation afforded 2-phenyl-3-undecene (Bpt 85° C. at 60 mmHg, 228 g, 38.1% yield, 97% purity). GC analysis determined the product to be a mixture of cis-2-phenyl-3-undecene (11.2%) and trans-2-phenyl-3-undecene (88.8%). 1H NMR (400 MHz, CDCl3, trans isomer) δ 0.95 (t, J=6.8 Hz, 3H), 1.25-1.55 (m, 13H), 2.07 (pquar, J=7.1 Hz, 2H), 3.48 (pquint, J=6.8 Hz, 1H), 5.40-5.60 (m, 1H), 5.61-5.70 (m, 1H), 7.20-7.30 (m, 3H), 7.31-7.37 (m, 2H). 1H NMR (400 MHz, CDCl3, cis isomer, selected resonances) δ 2.18 (m, 2H), 3.84 (m, 1H). 13C NMR (101 MHz, CDCl3, trans isomer) δ 15.7, 23.0, 24.1, 30.4, 30.4, 30.8, 33.0, 33.7, 43.2, 124.6, 125.8, 127.0, 128.0, 133.4, 144.8. 13C NMR (101 MHz, CDCl3, cis isomer, selected resonances) δ 23.7, 28.7, 30.4, 30.5, 30.9, 38.2, 124.5, 125.6, 127.0, 127.6, 133.3, 144.9.
Reaction 4. Preparation of 2-Phenyl-3-dodecene




A 5 liter jacketed flask equipped with a reflux condenser, vacuum adapter, and magnetic stir bar was charged with 1-decene (2.65 kg, 18.9 mol) and 3-phenyl-1-butene (0.50 kg, 3.78 mol). The reaction mixture was sparged with argon for 45 minutes, subjected to 4 mmHg vacuum, and heated to 45° C. Grubbs metathesis catalyst C827 (0.312 g, 0.378 mmol) in dichloromethane (3.0 mL) was subsequently added to the reaction mixture. The reaction mixture was allowed to stir at 45° C. and 4 mmHg vacuum for 6 hours. The reaction mixture was then cooled to room temperature and filtered through a plug of silica gel. The filter cake was washed with hexanes twice and all organic fractions combined and concentrated under reduced pressure. Vacuum distillation was not successful and the crude product (1.23 kg, 28% 2-phenyl-3-dodecene) was therefore used in subsequent transformations without purification. GC analysis determined the desired product to be a mixture of cis-2-phenyl-3-dodecene (15.1%) and trans-2-phenyl-3-dodecene (84.9%). An NMR sample was obtained by silica gel column chromatography using hexanes as the mobile. Fractions were analyzed by UV light, the UV active fractions were analyzed by GC where pure fractions of 2-phenyl-3-dodecene were combined and concentrated under reduced pressure. 1H NMR (400 MHz, CDCl3, trans isomer) δ 0.92 (t, J=7.0 Hz, 3H), 1.20-1.55 (m, 15H), 2.04 (pquar, J=7.2 Hz, 2H), 3.45 (pquint, J=6.8 Hz, 1H), 5.40-5.60 (m, 1H), 5.61-5.70 (m, 1H), 7.18-7.29 (m, 3H), 7.30-7.36 (m, 2H). 1H NMR (400 MHz, CDCl3, cis isomer, selected resonances) δ 2.15 (m, 2H), 3.81 (m, 1H). 13C NMR (101 MHz, CDCl3, trans isomer) δ 15.7, 23.0, 24.1, 30.4, 30.5, 30.7, 30.7, 33.0, 33.7, 43.1, 124.6, 125.8, 127.0, 128.0, 133.4, 144.8. 13C NMR (101 MHz, CDCl3, cis isomer, selected resonances) δ 23.7, 28.7, 30.6, 30.7, 30.9, 38.2, 124.52, 125.6, 127.0, 127.6, 133.3, 144.9.
Reaction 5. Preparation of 2-Phenyl-3-hexadecene




A 2 liter flask equipped with a reflux condenser and magnetic stir bar was charged with 1-tetradecene (125.0 g, 0.637 mol) and 3-phenyl-1-butene (252.5 g, 1.91 mol). The reaction mixture was sparged with argon for 45 minutes and heated to 45° C. Grubbs metathesis catalyst C827 (0.263 g, 0.032 mmol) in dichloromethane (2.0 mL) was subsequently added to the reaction mixture. The reaction mixture was allowed to stir at 45° C. under vacuum (4 mmHg) for 6 hours. The reaction mixture was filtered through a plug of silica gel. The filter cake was washed with hexanes twice and all organic fractions combined and concentrated under reduced pressure. GC analysis determined a 72% yield of 2-phenyl-3-hexadecene as a mixture of cis-2-phenyl-3-hexadecene (11%) and trans-2-phenyl-3-hexadecene (89%) isomers. Due to similar boiling points of 2-phenyl-3-hexadecene and 13-hexacosene (13C26), purification by vacuum distillation resulted in 138 g of 89% purity 2-phenyl-3-hexadecene which was subsequently hydrogenated without further purification.
Reaction 6. Representative example for the synthesis of internal olefins from the self-metathesis of alpha olefins




A 3 liter, 3-neck round bottom flask was equipped with a magnetic stir bar and fitted with a reflux condenser, vacuum adapter, and a rubber septum. The flask was charged with 1-octene (1.00 kg, 8.91 mol) and subjected to full vacuum (4 mmHg) at 40° C. for 30 minutes. A solution of Grubbs metathesis catalyst C848 in dichloromethane (25 ppm) was added via syringe to the reaction mixture under vacuum. After the reaction had reached completion, as judged by GC analysis, the crude mixture was filtered through a pad of silica gel and vacuum distillation afforded 7-tetradecene (7C14) (Bpt 71° C. at 0.15 mmHg, 761 g, 87.0% yield). 1H NMR (400 MHz, CDCl3) δ 0.83 (t, 6H, J=6.8 Hz), 1.25 (m, 16H), 5.30-5.45 (m, 2H, cis and trans isomers in a 23:77 ratio). 13C NMR (101 MHz, CDCl3) δ 14.31, 22.89, 27.48, 29.08, 29.23, 29.88, 30.00, 32.01, 32.85, 130.15, 130.62.
The same procedure was followed for the synthesis the following internal olefins: 9-octadecene (9C18), Bpt 148° C.-151° C. at 1.30 mmHg, 1H NMR (400 MHz, CDCl3) δ 0.94 (t, J=7.0 Hz, 6H), 1.25-1.45 (m, 24H), 1.97-2.12 (m, 4H), 5.35-5.47 (m, 2H, cis and trans isomers in a 26:74 ratio). 13C NMR (101 MHz, CDCl3) δ 14.1, 22.8, 27.4, 29.4, 29.5, 29.7, 29.7, 28.5, 30.0, 32.1, 32.8, 129.9, 130.4.
11-docosene (11C22), Bpt 176° C.-180° C. at 0.15 mmHg, 1H NMR (400 MHz, CDCl3) δ 0.94 (t, J=6.6 Hz, 6H), 1.25-1.45 (m, 32H), 1.97-2.12 (m, 4H), 5.36-5.46 (m, 2H, cis and trans isomers in a 19:81 ratio). 13C NMR (101 MHz, CDCl3) δ 14.2, 22.9, 27.4, 29.4, 29.5, 29.6, 29.8, 29.8, 29.9, 30.0, 32.1, 32.8, 129.9, 130.4.
Reaction 7. Synthesis of methyl substituted internal olefins from the self-metathesis of methyl substituted alpha olefins




A 100 mL, 2-neck round bottom flask was equipped with a magnetic stir bar and fitted with a reflux condenser and rubber septum. The flask was charged with 4-methyl-1-pentene (50.0 mL, 395 mmol) and Grubbs metathesis catalyst C848 (16.8 mg, 0.0198 mmol). The reaction was heated to 40° C. and sparged with argon for 2 hours then filtered through a pad of silica gel. Distillation afforded 2,7-dimethyl-4-octene (Bpt 152° C.-156° C., 17.2 g, 62.1% yield). GC analysis determined the product to be a mixture of trans-2,7-dimethyl-4-octene (83%) and cis-2,7-dimethyl-4-octene (17%). Trans-2,7-dimethyl-4-octene: 1H NMR (400 MHz, CDCl3) δ 0.94 (t, J=7.0 Hz, 12H), 1.64 (septet, J=6.7 Hz, 2H), 1.93 (m, 4H), 5.41 (m, 2H). 13C NMR (101 MHz, CDCl3) δ 22.4, 28.7, 42.3, 130.3. Cis-2,7-dimethyl-4-octene: 1H NMR (400 MHz, CDCl3) δ 0.94 (t, J=7.0 Hz, 12H), 1.64 (septet, J=6.7 Hz, 2H), 1.97 (m, 4H), 5.46 (m, 2H). 13C NMR (101 MHz, CDCl3) δ 22.5, 28.9, 36.6, 129.3.
Reaction 8. Synthesis of a mixture of Internal Olefins (IOs) by the self-metathesis of Alpha Olefins (AOs)




A 3 liter, 3-neck round bottom flask was equipped with a magnetic stir bar and fitted with a reflux condenser, vacuum adapter, and a rubber septum. The flask was charged with an equimolar ratio of 1-decene, 1-dodecene, and 1-tetradecene then heated to 40° C. and subjected to vacuum (75 mmHg) for 30 minutes. A solution of Grubbs metathesis catalyst C827 in dichloromethane (10 ppm C827 to AOs) was added via syringe to the reaction mixture under vacuum. After 16 hours the reaction was filtered through a pad of silica gel and unreacted α-olefins (AOs) were removed by vacuum distillation to afford C17-C26 internal olefins (IOs) in 83% yield. Internal olefins C17, C19, C21, C23 and C25 represented minor components of the mixture (i.e., <5% each). The odd carbon internal olefins were a result of double bond migration, followed by cross metathesis. This mixture was subsequently used in cross metathesis reactions with 3-phenyl-1-butene (Table 2, runs 16-19).
Reaction 9. Synthesis of 2-phenyl-3-decene by cross-metathesis of 3-phenyl-1-butene with 7-tetradecene




In an argon filled glovebox, 3-phenyl-1-butene (200 mg, 1.51 mmol), 7-tetradecene (446 mg, 2.27 mmol), and Grubbs metathesis catalyst were combined in a scintillation vial equipped with a magnetic stirbar. The vial was sealed, removed from the glovebox and stirred at 23° C. or 40° C. Samples were taken at various time points and analyzed by gas chromatography for conversion of 3-phenyl-1-butene (3P1B) and yield of 2-phenyl-3-decene (2P3D). Results are summarized in Table 1.

Krafft Point and CMC Data
Krafft Point or Krafft Temperature is defined as the minimum concentration of surfactant needed to form a micelle at a given temperature. Surfactants form micelles above their Krafft Point and the solubility in water increases abruptly. The Krafft point was determined by the abrupt increase in the electrical conductivity of as a function of temperature. The intersection of the two solubility lines is the Krafft Point.
The Critical Micelle Concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system go to micelles. The CMC is measured by the electrical conductivity-concentration curve at constant temperature. Table 5 contains the Krafft temperatures and CMC results.

To verify that the hydrovinylation of styrene produces 3-phenyl-1-butene and not 2-phenyl-1-butene, 3-phenyl linear alkyl benzene was synthesized by traditional methods and compared to 2-phenyl linear alkyl benzene by GC analysis. 3-Phenyl-1-butene yields 2-phenyl linear alkyl benzene while 2-phenyl-1-butene yields 3-phenyl linear alkyl benzene by our reported cross metathesis methodology.
3-Phenylundecane was synthesized by phenyl Grignard's addition to 3-undecanone, followed by hydrogenation. Equal amounts of 2-Phenylundecane (99.3% purity) and 3-phenylundecane (98.5% purity) were co-injected and analyzed by GC. The GC method and conditions is as described above. The results are represented in Table 6.

The reaction was then partitioned between water and ether (1:1 v/v, 4 mL), the organic phase separated and the aqueous phase extracted with diethyl ether (3×2.0 mL). The organic extracts were combined, dried over MgSO4, filtered, and the solvent was evaporated under reduced pressure. The product was purified by column chromatography to afford 1-(4-(hexadecan-2-yl)phenyl)-2,5,8,11,14-pentaoxapentadecane (9.6 mg, 15% yield, >95% pure).
