Asymmetric Hydrosilylation by Means of Homogeneous Catalysts with Chiral Ligands,enation of prochiral olefins using soluble rhodium(I) complexes with chiral phosphine ligands. Knowles . have found that the catalytic hydrogenation of .-acylamidocinnamic acids affords the corresponding amino acid derivatives with 80–95 percent enantiomeric excess (% e.e.) using rhodium complex
