    摘要: The present invention relates to the field of catalytic hydrogenation and, more particularly, to a process for the reduction by hydrogenation, using molecular H
    2 , of a C
    6 -C
    20 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
    34 -C
    60 bidentate diphosphine ligand (L2) coordinating the rhodium.
