OSMIUM COMPLEXES USABLE AS CATALYSTS FOR THE REDUCTION OF CARBONYL COMPOUNDS

摘要

The invention relates to new osmium complexes of the type [OsX2(P2)(diamine)] (P = phosphorus atom of a diphosphine; X = anionic ligand), and to preparation thereof. Said systems, in the presence of bases, have proved to be highly efficient catalysts for the hydrogenation of aldehydes and the enantioselective hydrogenation of various types of ketones.
