Hydride Fluxionality in Transiton Metal Complexes: An Approach to the Understanding of Mechanistic Features and Structural Diversities
Authors: Gusev Dmitry G. , Berke Heinz 
Published: July 2007

AbstractThe mechanisms of intramolecular dynamics in transition metal hydride complexes are surveyed in this review. The NMR data for a number of fluxional hydrides are interpreted in terms of principal and secondary topological changes of the coordinated ligands. The principal ligand motions can be further categorized as being of migratory (M) and replacement (R) type. Discussion of these ligand motions is followed by analysis of more complex rearrangements of hydride systems, in which both types are operative in multiple exchange processes. The attempted systematic approach appears to be a useful general mechanistic concept for the understanding of the fluxional behavior of hydride complexes.
Azidopentazole is Probably the Lowest‐Energy N8 Species – A Theoretical Study
Authors: Nguyen Minh Tho , Ha Tae‐Kyu 
Published: July 2007

AbstractAb initio molecular orbital calculations at the quadratic configuration interaction [QCISD(T)/6‐31G(d)] and coupled‐cluster theory [CCSD(T)/DZP] levels based on MP2/6‐31G(d) optimized geometries show that azidopentazole is likely to be the global minimum of the N8 isomers lying 13 and 18 kcal/mol below the acyclic diazidyldiimide and the cyclic pentalene analogue, respectively. Azidopentazole is characterized by a significant energy barrier to ring closure and is expected to be stable with respect to cycloreversion and thus constitutes the most realistic N8 target for a synthetic preparation.

Published: July 2007

AbstractBis(trimethylsilyl) peroxide (BTSP) and tert‐butyl hydroperoxide (tBuOOH) were activated by various oxo and peroxo complexes of molybdenum, tungsten, and vanadium as catalysts for the sulfoxidation of thianthrene 5‐oxide (SSO). A screening of a number of phosphane oxide and amine oxide ligands revealed that BTSP was most efficiently activated by the [MoO5(OPtBu3)] complex. The best results for tBuOOH as oxygen source were achieved with the vanadates [VO(OR)3] (R = tBu, iPr). Comparative selectivity and rate data for the stoichiometric and catalytic sulfoxidations of SSO mediated by the MoO5L complex (L = OPtBu3, OPnOct3, ONnBu3, ONnOct3) suggest that the bisperoxo metal complex is the active oxygen transfer species.

Published: July 2007

AbstractThe hydridoruthenium(II) complexes [RuHCl(H2)(SbiPr3)3] (2) and [RuH2(H2(SbiPr3)3] (3), containing dihydrogen as ligand, were prepared from [RuCl2(C8H12)]n (1) as the starting material. Compound 3 reacts with CO by displacement of H2 to yield [RuH2(CO)(SbiPr3)3] (4) and with C2H4 to give both [RuH2(C2H4)2(SbiPr3)2] (5) and [RuH2(C2H4)(SbiPr3)3] (6), the latter as the more stable and isolable product. Treatment of 3 with propene leads to the formation of [Ru(η3‐C3H5)2] (7) while the reaction of 3 with butadiene affords the pentacoordinated ruthenium(0) compound [Ru(η4‐C4H6)2(SbiPr3)] (8). The molecular structure of the bis‐(allyl) complex 7 was determined by X‐ray crystallography.

Authors: Lomme Petra , Roth Martin , Englert Ulli , Paetzold Peter 
Published: July 2007

AbstractThe aza‐closo‐boranes ArNB9H9 (1, Ar = p‐ClC6H4) and MeNB11H11 (2) were brominated, iodinated, or methylated under Friedel‐Crafts conditions to give ArNB9H4Br5 (3), ArNB9H7I2 (4), ArNB9H4Me5 (7), MeNB11H10Br (5), MeNB11H10I (6), and MeNB11H5Me6 (9), respectively. The upper boron belt adjacent to nitrogen is not involved in the substitution reactions with 1 and 2. The antipodal position and the lower belt are attacked by electrophiles in the case of 1; the antipodal position is the preferred one in the case of 2. By prolongated action of triflic acid on the methylated species 7 and 9, one methyl group is replaced by the triflate group to give ArNB9H4Me4(OTrf) (8) and MeNB11H5Me5‐(OTrf) (10) with this group in the positions 6 and 12, respectively. The NMR data indicate the cluster symmetries Cs (4, 8), C4v (3, 7), and C5v (5, 6, 9, 10). Crystal structure investigations of 5 (space group Cc) and 10 (space group C2/c) showed that the molecular dimensions of the NB11 skeleton are comparable to those of closo, ‐(PhCH2)NB11H11.
Crystal Structure of a Representative Mixed Adduct of Trimethylaluminium and a Lithium Amide and a Theoretical MO Study on Model Systems
Authors: Armstrong David R. , Craig Fiona J. , Kennedy Alan R. , Mulvey Robert E. 
Published: July 2007

AbstractReaction of the simple alane adduct [Me3Al · HN(CH2Ph)2] (2) with the lithium amide [(PhCH2)2NLi] leads to the formation of the mixed adduct [Me3Al · (PhCH2)2NLi · HN(CH2Ph)2] (1). The crystal structures of 1 and 2 are reported. Exhibiting a four‐membered, mixed‐metal, mixedanion ring‐core, the structure of 1 is unusual in containing a monomeric lithium dibenzylamide fragment. Such fragments generally convert to aza‐allyl derivatives, so its existence here can be attributed to the stabilising effect of the attached Me3Al ligand. Crystalline 2 adopts the classical, distorted‐tetrahedral arrangement of simple monomeric alane adducts. Ab initio MO calculations on model systems show that mixed adduct formation from Me3Al and Me2NLi is exothermic, while further reaction to give Me2AlNMe2 and MeLi (i.e., complete transmetallation) is endothermic.

Authors: Gemünd Birgit , Nöth Heinrich , Sachdev Hermann , Schmidt Martin 
Published: July 2007

AbstractThe crystal and molecular structures of a series of N‐phenyl‐substituted lithium hydrazides were determined in order to investigate possible Li···Ph π interactions. These are pronounced when there are no donor molecules present to solvate the Li centers. An η6‐Li···Ph interaction is particularly distinct in tetrameric (Me3Si)2N–N(Ph)Li but also in trimeric Ph2N–N(SiMe3)Li Deprotonation of N,N′ ‐diphenylhydrazine with butyllithium in ether resulted in the formation of Ph(Li)N–N(Ph)Li · 2 LiNPh2 · 2 OEt2 with phenyl group migration and N–N bond cleavage by a redox process. An increase of the size of the cations, as shown for Ph(Me3‐Si)N–N(Ph)Na · NH3 and the caesium salt (Me3‐Si)2N–N(Ph)Cs · nTHF, results in increased coordination of the metal ion to the phenyl group. The caesium compound forms a three‐dimensional network. Channels along the c axis are partially filled with THF molecules.

Authors: Weigand Wolfgang , Wünsch Ralf 
Published: July 2007

AbstractThe synthesis and coordination chemistry of sulfenic, thiosulfinic, and thiosulfonic acid anions are reviewed. Different approaches, which yield the platinum(II) and ruthenium(II) complexes containing the anionic sulfur(0), sulfur(II), and sulfur(IV) oxid ligands, are described. The oxidative addition of thiosulfinates or N‐sulfinyl phthalimides to platinum(0) complexes L2Pt(C2H4) [L = PPh3, 1/2 PPh2CH2CH2PPh2, 1/2 (R,R)‐(–)‐DIOP, 1/2 (C5H4PPh2)Fe(C5H4PPh2) leads to sulfenato complexes; those of N‐thiosulfinyl phthalimidies or trisulfid 1‐oxides afford the thiosulfinato complexes. Moreover, the reactions of CpRu(PPh3)(L)(SH) (L = CO, PPh3) with N‐sulfinyl phthalimides forming the thiosulfinato moiety, are reported. The spectroscopic, structural and chemical properties of these complexes are discussed.
Optically Active Titanium Complexes Containing Linked Amido‐cyclopentadienyl Ligands: Their Use as Asymmetric Hydrogenation Catalysts
Authors: Okuda Jun , Verch Sabine , Spaniol Thomas P. , Stürmer Rainer 
Published: July 2007

AbstractOptically active titanium complexes of the formula Ti(η5:η1−C5R4SiMe2NCHMePh)Cl2 (R = H, Me), containing the cyclopentadienyl ligand linked to a chiral 1‐phenylethylamido moiety, were synthesized and characterized in both enantiomerically pure forms. A single‐crystal X‐ray structural analysis of (S)()Ti(η5:η1−C5H4SiMe2NCHMePh)Cl2 shows a conformation in which the phenyl group is turned away from the metal center. NOE measurements suggest that a related structure is retained in solution. Upon activation with n‐butyllithium, these complexes show hydrogenation activity toward imines with slight enantioselectivity.

AbstractIt is unequivocally shown that acetophenone, an oxidation product in the titanium zeolite‐catalyzed oxidation of α‐methylstyrene, derives from 2‐hydroperoxy‐2‐phenyl‐1‐propanol as intermediate, which was detected and isolated in this reaction for the first time.
Synthesis, Structure and Reactions of the Homoleptic Alkyne Nickel(0) Complex (Alkyne)4Ni3 (Alkyne: 2‐methyl‐4‐trimethylsilyl‐3‐butyn‐2‐ol)
Authors: Klettke Thomas , Walther Dirk , Schmidt Andreas , Görls Helmar , Imhof Wolfgang , Günther Wolfgang 
Published: July 2007

AbstractTreatment of (cdt)Ni (cdt: cyclododeca‐1,5,9‐triene) with 2 equivalents of 2‐methyl‐4‐trimethylsilyl‐3‐butyn‐2‐ol leads to the selective formation of the homoleptic complex (alkyne)4Ni3 (compound 3), which can be isolated in excellent yields. The solid‐state structure of 3 exhibits three Ni centers, forming a bent Ni3 chain connected by two bridging alkynes. The other two alkynes are terminally coordinated. Additionally, the trimeric units are stabilized by three intramolecular hydrogen bonds. Two intermolecular hydrogen bonds connect the trimeric units to form a polymer rope. According to the 13C‐ and 1H‐NMR spectra in THF the structure of the complex 3 in solution is very similar to that in the solid state. The reaction of 3 with some alkynediols and with 2,5,5‐trimethylhex‐3‐yn‐2‐ol affords compounds of the type (alkyne)2Ni. Cot (cot: 1,3,5,7‐cyclooctatetraene) converts 3 into [(cot)Ni]2, which in turn reacts with 2,5‐dimethylhex‐3‐yne‐2,5‐diol to form the dimeric complex (alkyne)2Ni2(cot) 6. X‐ray analysis of 6 reveals a very symmetrical structure in which cot connects both Ni(0) centers at opposite sides of the ring system.
Hydride Addition to Coordinated S2CPR3 Ligands in Mononuclear Mn and Re Complexes: Phosphane‐dithioformate Adducts as Five‐electron Bridging Ligands

Published: July 2007

AbstractThe cationic tetracarbonyl complex cis‐[Mn(CO)4‐(S2CPCy3)]+ undergoes addition of hydride ion to the central carbon of the S2CPR3 ligand to afford, after spontaneous dimerization with loss of CO, the dimer [Mn2(CO)6{μ‐S2C(H)PCy3}2] (5a), which was characterized by analytical and spectroscopic methods as well as by X‐ray diffraction. In the molecule of 5a each S2C(H)PCy3− ligand is coordinated to one manganese in an η2‐S,S′ chelate fashion, and one sulfur of each ligand serves as a bridge to bind the other manganese atom, thus forming a distorted Mn2S2 square. This appears to be a very stable arrangement. Compound 5a can be more easily prepared by treating the perchlorato complex [Mn(CO)3(S2CPCy3)(OClO3)] (2a) with NaBH4. This procedure is general and can be used for the preparation of several derivatives containing either manganese or rhenium [M2(CO)6{μ‐S2C(H)PR3}2] 5a–d. The reaction of cationic tricarbonyl complexes [M(CO)3(S2CPR3)(PPh3)]PF6 (M = Mn, Re) with NaBH4 produced the same dimers 5a or 5c by displacement of the PPh3 ligand. Treatment of the dimer 5a with excess PEt3 or P(OMe)3 leads to the cleavage of the bridges and loss of one CO and the PR3 group from the S2C(H)PR3 unit to afford ultimately the dithioformate complexes [Mn(CO)2(S2CH)(L)2] [L = PEt3, P(OMe)3].

Published: July 2007

AbstractReactions of C,O‐dilithium reagents 1 (M = M′ = Li) or C,O‐lithium‐sodium reagents 1 (M = Li, M′ = Na) with chlorophosphanes afford C,O‐disubstitution products 2 or phosphanylphenolates 3 which are treated subsequently with ClSiMe3 to give 4‐methyl‐ and bulky 4,6‐di‐tert‐butyl substituted o‐phosphanylphenol silyl ethers 4. These were applied for the preparation of the corresponding o‐phosphanylphenols 5, mainly P‐asymmetric derivatives. Limitations and side reactions by use of 1 in the above synthesis are discussed. Acid‐base properties, pH‐dependent solubility in water/hexane, and substitution reactions at oxygen and phosphorus of selected representatives of 5 are reported. An example for the separation of enantiomers by esterification with (1S)‐()‐camphanic acid chloride is given. IR studies revealed intramolecular PHO bonds and 2J(PC) the preferred trans arrangement of the phenoxy group in solution. In the solid state, inter‐ and intramolecular PHO bonds were detected by X‐ray structure analysis. The trans arrangement of the phenoxy group is preserved. Because of steric hindrance, the O substituents are tilted towards the phosphorus atom and thus induce large through‐space coupling constants. The PSn distance of 336.9 pm in the bulky substituted OSnMe3 moiety 8h is however too large for the formation of genuine intramolecular coordination. The versatility of o‐hydroxyarylphosphanes and objectives of further studies are shown by preliminary results on complex formation and applications of these phosphanes in catalysis.
Crystal Structure, Solid‐state Polymerization, and Ionic Conductivity of Alkali Salts of Unsaturated Carboxylic Acids, 4. Investigations on Lithium Sorbate
Authors: Schlitter Stephan M. , Beck Horst P. 
Published: July 2007

AbstractThe structure of lithium sorbate (C6H7LiO2) was determined by single‐crystal X‐ray diffraction. It may be divided into organic and inorganic layers. The ionic part of the structure consists of a two‐dimensional network of corner‐ and edge‐sharing lithium oxotetrahedra, a structural pattern already known from other lithium carboxylates. Irradiation of the substance with X‐rays or its thermal treatment results in the formation of a polymer exhibiting ionic conductivity at higher temperatures. Due to the rather large distances between potentially reactive atoms the polymerization results in a structural breakdown. Nevertheless, during the solid‐state polymerization preferred orientations of building units are partially preserved. The probable course of the polymerization and the structure of the resulting polymer are discussed.
Synthesis, Structure and Conformation of cis‐ and trans‐(μ‐1,6‐Dimethylheptalene)bis(tricarbonyliron)
Authors: Grimm Felix W. , Hafner Klaus , Lindner Hans J. 
Published: July 2007

AbstractThe reaction of 1,6‐dimethylheptalene (2) with Fe2(CO)9 affords two binuclear iron complexes 4a and 4b, each bearing two tricarbonyliron moieties, in trans and cis orientation, respectively. The reaction leads additionally to the formation of the monocomplexed compound 3. NMR studies indicate that the heptalene moiety of the new compounds is a π‐bond isomer of 2, and this is clearly attributable to steric factors. Single‐crystal X‐ray structure analyses of the metal complexes 4a and 4b confirm that the Fe(CO)3 fragments adopt trans and cis geometries, respectively, with respect to the plane of the carbocycle. The ring systems of the two isomers adopt different conformations in the solid state. In the case of 4a, a hitherto unknown chair‐like conformation is determined, whereas in complex 4b the ring system shows a twisted double boat conformation.

— Oxidative Addition of Electrophilic Derivatives of α‐Amino Acids to Platinum(II) and Cobalt(I) Complexes: α‐Transition‐Metallated Amino Acids

Herrn Professor Dr. Hans Georg von Schnering zum 65. Geburtstag gewidmet.
The addition of methyl α‐bromohippurate to PtMe2(bipy) gives the α‐metallated amino acid derivative (bipy)‐Me2(Br)PtC(H)(NHCOPh)(CO2Me) as a mixture of isomers 1a, b of which the trans adduct 1a was characterized by X‐ray diffraction. Methyl α‐bromohippurate and N‐Boc‐O‐tosylserine methyl ester are added to [Co(py)(DH)]− (DH = dimethylglyoxime, diphenylglyoxime) to give cobalt(III) complexes 2–5 with a cobalt‐carbon bond.

Organo‐Zinc Phosphaneiminato Complexes with Heterocubane StructureThe organo‐zinc heterocubanes [ZnR(NPMe3)]4 with R = CH3 (1) and n‐C4H9 (2) were prepared by the reaction of [ZnBr(NPMe3)]4 with MeLi and nBuLi, respectively, in hexane solution. In a similar reaction of nBuLi with [ZnI(NPMe3]4 the phosphaneiminato complex [Zn4I(nBu)4(NPMe3)3] (3) is formed. 1–3 were characterized by IR, NMR and MS spectroscopy, and by crystal‐structure determinations. 1 and 2 possess heterocubane structures in which the zinc atoms are linked via μ3‐N bridges of the phosphaneiminato groups, and all bond angles in the Zn4N4 core are close to 90°. A distorted heterocubane structure is observed for 3 with one of the NPMe3 moieties replaced by an iodine atom.
Generation and Synthetic Application of Metallated Methyl Isopropenyl Ether, A Substitute for Acetone Enolate
Authors: Taherirastgar Foroogh , Brandsma Lambert 
Published: July 2007

AbstractMethyl isopropenyl ether (1) has been metallated at low temperature with a 1:1 molar mixture of n‐BuLi/t‐BuOK in THF‐hexane, and subsequently functionalized with a variety of electrophilic reagents. At temperatures higher than – 30°C, the metallated methyl isopropenyl ether (2) decomposes with formation of allene. When the suspension of 2 is allowed to warm up to room temperature in the presence of an additional equivalent of n‐BuLi, the intermediary allene is converted into 1‐propynyllithium (2c), which reacts with propylthiocyanate to give 1‐propylthio‐1‐propyne (4). Some of the functionalization products were subjected to acidic hydrolysis affording the expected methyl ketones.
A Structural Study of Selenobenzamides: Crystal Structures and Dynamic 13C NMR
Authors: Otten Pieter A. , Gorter Syb , Gen Arne Van Der 
Published: July 2007

AbstractThe solid‐state structures of (p‐bromoselenobenzoyl)morpholine (2a) and [p‐(dimethylamino)selenobenzoyl]morpholine (2b) were determined by X‐ray diffraction. Both molecules show a flat selenoamide group. The larger contribution of resonance stabilization by the aromatic ring carrying the p‐dimethylamino substituent is reflected by the smaller interplanar angle Θ between the aromatic ring and the selenoamide group [53.3(1)° vs. 81.1(1)°] and by the shorter length of the CSe bond [1.824(5) Å vs. 1.840(3) Å]. The Gibbs free energy of activation of C‐N bond rotation (ΔG≠rot) of five p‐substituted (selenobenzoyl)morpholines was determined by dynamic 13C NMR. The activation barriers were found to range from 61.6 kJ/mol (X = NNMe2) to 75.1 kJ/mol (X = H). The ΔG≠rot values of the corresponding (thiobenzoyl)morpholines were found to be from 3.2 kJ/mol (X = NMe2) to 5.0 kJ/mol (X = H) lower. In both cases, ΔG≠rot showed an excellent linear Hammett correlation with s̀+p.
Asymmetric Catalysis, 105. Stereoselective Hydrogenation of Folic Acid with Immobilized Optically Active Rhodium(I)/Diphosphane Catalysts
Authors: Brunner Henri , Bublak Petra , Helget Martina 
Published: July 2007

AbstractFor the hydrogenation of the CN bonds in the pyrazine ring of the vitamin folic acid (1) optically active rhodium(I)/diphosphane complexes immobilized on supports such as silica gel or Al2O3 were used. The reduction was carried out at 50 bar hydrogen pressure in an aqueous solution buffered to pH 7. Thus, 5,6,7,8‐tetrahydrofolic acid (2) was obtained which contains a new asymmetric center at C‐6 of the pterine system. Therefore, in combination with the (S) configuration of the natural L‐glutamic acid part of the molecule two diastereomers with (6S,S) and (6R,S) configuration arise. The relatively unstable tetrahydrofolic acid (2) was converted into its 5‐formyl derivative folinic acid (4) by treatment with methyl formate/formic acid in a 5:1 mixture of DMSO/pyridine. The Ca salt of folinic acid (4) is the widely used drug leucovorin. The diastereomers were separated by silica gel HPLC. To the column bovine serum albumine (BSA) is covalently bound. With optically active rhodium(I)/diphosphane catalysts, immobilized on silica gel supports, a diastereoselectivity of up to 90% could be achieved in the hydrogenation of folic acid (1).
Conformational Mobility and Preferences of Allyl‐Type Organometallic Intermediates: Dodec‐2‐enylpotassium
Authors: Franzini Livia , Moret Etienne , Schlosser Manfred 
Published: July 2007

AbstractAlk‐2‐enylpotassium compounds having the endo conformation are synthetically very valuable precursors of (Z)‐olefinic derivatives substituted at the outward allylic position. They may be generated by „stereoconservative’︁ metalation of the readily available (Z)‐alk‐2‐enes by using the superbasic mixture of butyllithium and potassium tert‐butoxide or by metalation under similar conditions of stereorandom mixtures of alk‐2‐enes or alk‐1‐enes followed by torsional isomerization of the concomitantly formed exo conformers to the thermodynamically more stable endo species. The principal factors that dictate the rate and the extent of the endo/exo equilibration are the substrate geometry, the solvent, the temperature, the reagent stoichiometry, and catalysis.

AbstractA series of isothiazole‐based potential ligands bearing substituents with additional donor sites in the 5‐position of the heterocycle was synthesized [3‐Me‐5‐R‐C3HNS; R = CHN(CH2)2py (1), CHNCH2py (2), CH2N(CH2CH2NEt2)2 (4), (CH2)2SMe (5)]. Upon reaction with AgO3SCF3 they formed complexes [(1)AgOSO2CF3]2 (6), [(2)AgOSO2CF3]2 (7), [(4)Ag]2+2(O3SCF−3)2 (8) and [(5)AgOSO2CF3]2 (9), respectively. 6, 8 and 9 were shown by X‐ray structural analyses to consist of dimeric units L2Ag2+2, either discrete (8), coordinated by terminal CF3SO−3 units (6). In 8 and 9 the isothiazole moiety is bonded to the metal center via the ring‐N. The coordination potential of the isothiazole heterocycle is discussed.
