Article abstract of DOI:10.1007/BF00961341

A study has been made of the asymmetric hydrosilylation of acetophenone by diphenylsilane under the influence of rhodium complexes with chiral phosphites.The enantioselective nature of the reaction depends on the phosphite structure, the acetophenone/rhodium and ligand/rhodium ratios, and the temperature.The maximum optical yield (24percent) is attained on the complex 2/(S,S)-2-ethoxy-4,5-dicarbisopropoxy-1,3,2-dioxaphospholane.
