Asymmetric Hydrogenation Catalysts

Iridium complexes with chiral N,P ligands have established themselves as efficient catalysts for the asymmetric hydrogenation of olefins, with largely complementary scope to Rh and Ru diphosphane complexes. In contrast to Rh and Ru catalysts, they do not require a coordinating polar group next to the C=C bond. Initial experiments with cationic phosphanyloxazoline (phox) complexes ([Ir(1)(cod)]X...

Selective Hydrogenation With Copper Catalysts: II. Kinetics

To explain the unusually high selectivity of copper catalysts toward linolenate, model compounds were hydrogenated (150 C and atmospheric pressure) and the reaction products analyzed. Products varied depending upon location of the double bonds. Monoenes were not reduced by copper chromite except when the double bond was next to a carboxyl group. Dienes with isolated double bonds also were not r...

Olefin Hydrogenation with Iron Carbonyls as Catalysts

O estudo de [Fe(CO)5], [Fe2(CO)9] e [Fe3(CO)12] como precursores catalíticos nas reações de hidrogenação do ciclohexeno e 1-hexeno foi efetuado. Um reator fotoquímico com fluxo de H2 e irradiação UV-vis foi usado no processo. Os espectros infravermelho das amostras mostraram a formação de [Fe(CO)4(olefina)] e [HFe(CO)3(π-alila)] como intermediários. A atividade mostrada do [Fe2(CO)9] na hidroge...

Nickel Hydrogenation Composite Catalysts Modified by Zirconium in Competitive Benzene Hydrogenation: Effect of Modifiers

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desor...

Alkene Metalates as Hydrogenation Catalysts

First-row transition-metal complexes hold great potential as catalysts for hydrogenations and related reductive reactions. Homo- and heteroleptic arene/alkene metalates(1-) (M=Co, Fe) are a structurally distinct catalyst class with good activities in hydrogenations of alkenes and alkynes. The first syntheses of the heteroleptic cobaltates [K([18]crown-6)][Co(η4 -cod)(η2 -styrene)2 ] (5) and [K(...
