SELECTIVE HYDROGENATION OF ALDEHYDE WITH RU/BIDENTATE LIGANDS COMPLEXES

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 alcohol 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 N2P2O2, wherein the coordinating atoms N2 are provided by a first bidentate ligand, the 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.
