Title (EN) RUTHENIUM COMPLEXES OF PHOSPHINE-AMINOPHOSPHINE LIGANDS
(FR) COMPLEXES DE RUTHÉNIUM DE LIGANDS PHOSPHINE-AMINOPHOSPHINE
Abstract:
(EN) Disclosed are ruthenium complexes of phosphine-aminophosphine ligands that may be used to catalyze large number of reactions of a wide variety of substrates such as asymmetric hydrogenations, asymmetric reductions, asymmetric hydroborations, asymmetric olefin isomerizations, asymmetric hydrosilations, asymmetric allylations, and asymmetric organometallic additions. Also disclosed is a process for the preparation of the ruthenium complexes and processes for the enantioselective asymmetric hydrogenations of 1,3-dicarbonyl, &agr;-hydroxycarbonyl, and &bgr;-hydroxycarbonyl compounds to produce the corresponding hydroxy­carbonyl, 1,2-diol, and 1,3-diol compounds, respectively, using the ruthenium complexes to catalyze the hydrogenation.

Présentation également d'un processus pour la préparation de complexes de ruthénium et de processus pour les hydrogénations énantiosélectives asymétriques de composés de di-carbonyle 1,3, d'hydroxycarbonyle &agr; et d'hydroxycarbonyle &bgr; pour produire l'hydroxy-carbonyle correspondant, les composés diol 1,2, et diol 1,3, respectivement, utilisant les complexes de ruthénium pour catalyser l'hydrogénation.
