Abstract
A process for the hydrogenation, using molecular hydrogen (H2) of a catalytic system, wherein the catalytic system includes a base and a complex of formula (II): Ru(P2N2)Y2 (II) wherein Y represent simultaneously or independently a hydrogen or halogen atom, a hydroxy group, or an alkoxy, carboxyl or other anionic radical, and P2N2 is a tetradentate diimino-diphosphine ligand.
Claims19
A process for hydrogenation, using molecular hydrogen (H2), of a C═O or C═N double bond of a substrate, in the presence of a catalytic system, wherein the catalytic system comprises a base and a ruthenium complex with a tetradentate diimino-diphosphine ligand.
