Abstract:
1. A process for the hydrogenation, using molecular hydrogen (H 2 ), of a C═O double bond of a substrate into the corresponding hydrogenated compound, in the presence of a complex and a base, said process being characterized in that said complex is of formula (II): wherein X and Y represent, simultaneously or independently, a hydrogen or halogen atom, a hydroxy radical, or a C1 to C8 alkoxy or acyloxy radical; m is 1 or 2, wherein w is 1, m is 1; or wherein w is 0, m is 2; L represents a bidentate N-P ligand of general formula in which formula (III) the dotted line indicates a single or double bond; n is an integer from 1 to 4; z is 0 or 1 when the carbon-nitrogen bond with the dotted line represents a double, respectively single bond; R′ represents a hydrogen atom, a linear, branched or cyclic C R R wherein R the possible substituents of R wherein the substrate reduced is of formula: wherein W is an oxygen atom, and R the possible substituents of R wherein W, R
