The present invention relates to the field of catalytic hydrogenation and, more particularly, to a process for the reduction by hydrogenation, using molecular H2, of a C6-C20 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 C34-C60 bidentate diphosphine ligand (L2) coordinating the rhodium.
