Mixtures of chiral and achiral monodentate ligands in asymmetric Rh-catalyzed olefin hydrogenation: reversal of enantioselectivity

The recently described method of combinatorial asymmetric transition metal catalysis based oil the use of mixtures of chiral monodentate P-ligands has been extended to include mixtures of chiral and a chiral monodentate P-ligands, reversal of enantioselectivity in Rh-catalyzed olefin hydrogenation being possible in appropriate cases.
