The present invention relates to processes for the reduction by hydrogenation, using molecular H2, of a C5-C20 substrate containing one or two aldehydes functional groups into the corresponding alcohols or diol, characterized in that said process is carried out in the presence of - at least one catalyst or pre-catalyst in the form of a ruthenium complex having a coordination sphere of the N1P3O2, wherein the coordinating atom N and one coordinating atom P are provided by a first bidentate ligand, and the two other coordinating atoms P2 are provided by a second bidentate ligand and the coordinating atoms O2 are provided by two non- linear carboxylate ligands; and - optionally of an acidic additive.
