PROCEDE DE PREAPARATION DE CATALYSEURS D'HYDROFORMYLATION ET D'HYDROGENATION A PARTIR DE COMPLEXES BINUCLEAIRES DU RHODIUM

摘要

The present invention relates to hydrogenation and hydroformylation catalysts based on a binuclear rhodium complex having the formula: wherein X and X' can be the same or different; when X and X' are the same they are organic tertiary phosphite groups and when different X is a CO group and X' is an organic tertiary phosphite group or an aromatic phosphine group, and SY and SY' are thiolato groups. The invention also comprises the processes of hydroformylation and hydrogenation using such catalytic complex.
