Abstract

Abstract 2, 3-Bis (dimenthylphosphino) maleic anhydride and the phenylimide derivative have been prepared from 2, 3-dichloromaleic anhydride and 2, 3-dichloro-N- phenylmaleimide, respectively, and dimenthyl (trimethylsilyl) phosphine. These compounds have been used as ligands for Rh complexes and have been tested in the asymmetric hydrogenation of α-acetamidocinnamic acid, methyl-α-acetamidocinnamate and itaconic ...
