Considered along with NMR and tensiometric data, the findings are interpreted in terms of a basic hydride route in which an initially formed, dinuclear, molecular hydrogen complex (eta(2)-H-2)Ru(dppb)(mu-Cl)(3)RuCl(dppb) transfers both hydrogens to the styrene.}, keywords = {ASYMMETRIC HYDROGENATION, BINAP, CATALYSIS, COMPLEXES, DIHYDROGEN, dihydrogen complexes, HYDROGENATION, KINETICS, LIGANDS, phosphine, ruthenium, RUTHENIUM(II) COMPLEXES, SELECTIVE, STYRENE, UNSATURATED CARBOXYLIC-ACIDS}, isbn = {0022-328X}, url = {://A1995QG25400022}, author = {Joshi, A.
