HYDROGENATION OF DIENALS WITH RHODIUM COMPLEXES UNDER CARBON MONOXIDE FREE ATMOSPHERE

摘要

26203460The present invention relates to the field of catalytic hydrogenation and more particularly to a process for the reduction by hydrogenation using molecular H of a C C conjugated dienal into the corresponding deconjugated enal characterized in that said process is carried out in the presence of a catalytic system comprising at least a base and at least one complex in the form of a rhodium complex comprising a C C bidentate diphosphine ligand (L2) coordinating the rhodium.
