✦ Synopsis
Readily available peralkyl aminophosphinephosphinite ligands (alkyl-AMPP*) give neutral rhodium complexes active for the catalytic reduction of some activated ketones under atmospheric hydrogen pressure at ambient temperature (ee = 80 %).
Asymmetric hydrogenation of ketones has been performed under rather drastic conditions on rhodium diphosphine catalysts in moderate optical yieldsl.
