Photolysis of hexacarbonylmetal(0) complexes of the Group 6 elements in the presence of vinylferrocene in an n-hexane solution at -15 degreesC yields pentacarbonyl (eta(2)-vinylferrocene)metal(0) complexes as the sole photo-substitution product, different from the general reaction pattern observed for the same Group 6 metal carbonyls with other olefins. M(CO)(5)(eta(2)-vinylferrocene) complexes (M = Cr, Mo, W) could be isolated from the solution and characterized by using spectroscopic techniques. The complexes were found to be not very stable and their stability increases in the order Cr < Mo < W. The relatively stable W(CO)(5)(eta(2)-vinylferrocene) could be isolated as-a pure solid and characterized by elemental analysis, MS, IR and NMR spectroscopy, while the solid samples of the less stable Cr(CO)(5)(eta(2)-vinylferrocene) and Mo(CO)(5)(eta(2)-vinylferrocene) complexes were found to be contaminated with free vinylferrocene and characterized only by using IR and NMR spectroscopy.

Carbonyltungsten(0) complexes of acryloylferrocene: Synthesis and characterization
Boga, Dilek Ayse; Özkar, Saim (Elsevier BV, 2006-07-15)
Photolysis of hexacarbonyltungsten(0) in the presence of acryloylferrocene in n-hexane solution at 10 C yields pentacarbonyl(eta(2)-acryloylferrocene)tungsten(0) (1) as the only photo-substitution product, different from the general reaction pattern observed for the Group 6 metal carbonyls with other olefins. W(CO)5(eta(2)-acryloylferrocene) (1) decomposes in solution to the parent hexacarbonyltungsten(0) and free acryloylferrocene. Trimethylphosphite was introduced as ligand into the molecule to increase t...
Benzaldehyde lyase-catalyzed enantioselective carboligation of aromatic aldehydes with mono- and dimethoxy acetaldehyde
Demir, Ayhan Sıtkı; Sesenoglu, O; Dunkelmann, P; Muller, M (American Chemical Society (ACS), 2003-06-12)
Benzaldehyde lyase from the Pseudomonas fluorescens catalyzes the reaction of aromatic aldehydes with methoxy and dimethoxy acetaldehyde and furnishes (R)-2-hydroxy-3-methoxy-1-arylpropan-1-one and (R)-2-hydroxy-3,3-dimethoxy-1-arylpropan-1-one in high yields and enantiomeric excess via acyloin linkage. Aromatic aldehydes and benzoins are converted into enamine-carbanion-like intermediates prior to carboligation.

Reaction of furfurylamine with 1 or 2 equivalents of PPh2Cl in the presence of Et3N, proceeds under anaerobic conditions in thf to give furfuryl-2-(N-diphenylphosphino)amine, Ph2PNHCH2-C4H3O, 1 and furfuryl-2-(N,N-bis(diphenylphosphino)amine), (Ph2P)(2)NCH2-C4H3O, 2, respectively. The reactions of 1 and 2 with MCl2(cod) (M = Pd, Pt; cod = 1,5-cyclooctadiene) or Pt(CH3)(2)(cod) yield complexes [M(Ph2PNHCH2-C4H3O)(2)Cl-2] (M= Pd 1a, Pt 1b), [Pt(Ph2PNHCH2-C4H3O)(2)(CH3)(2)] (1c), and [M((Ph2P)(2) NCH2-C4H3O)Cl...
Organosilanols as Catalysts in Asymmetric Aryl Transfer Reactions
Özçubukçu, Salih; BOLM, Carsten (American Chemical Society (ACS), 2005-03-01)
Various ferrocene-based organosilanols have been synthesized in four steps starting from achiral ferrocene carboxylic acid. Applying these novel planar-chiral ferrocenes as catalysts in asymmetric phenyl transfer reactions to substituted benzaldehydes afforded products with high enantiomeric excesses. The best result (91% ee) was achieved in the addition to p-chlorobenzaldehyde with organosilanol 2b, which has a tert-butyl substituent on the oxazoline ring and an isopropyl group on the silanol fragment.

The hexacarbonyls of chromium, molybdenum, and tungsten react with tricyclo[6.3.0.0(2,7)]undeca-3,5-diene upon UV irradiation in a first step to tetracarbonyl-eta-4-tricyclo[6.3.0.0(2.7)]undeca-3,5-diene-chromium(0) (1), -molybdenum(0) (2) and -tungsten(0) (3). By longer irradiation, dicarbonyl-bis(eta-4-tricyclo[6.3.0.0(2.7)]undeca-3,5-diene)molybdenum(0) (4) and -tungsten(0) (5) are formed. The complexes were purified by chromatography and studied by IR, H-1, and C-13 NMR spectroscopy. The C-13 NMR signal...
