Abstract
A method of using a chiral phosphorus-containing ligands comprising at least one amine radical and at least one dihydrocarbylphosphioxy radical of the formula W=OP (R).sub.2 ; from the group consisting of: those of the formula ##STR1## those of the formula ##STR2## those of the formula ##STR3## those of the formula ##STR4## in a hydrogenation reaction for the synthesis of optically active organic compounds comprising reacting at least one organic compound that does not possess a center of asymmetry with (A), on the one hand, at least one transition metal complex of the formula MZq in which M is a metal in group VIII of the Periodic Classification, q is the coordination number of the metal M, and Z is an atom or molecule capable of complexing the metal M and (B), on the other hand, at least one ligand L.
