and H-phosphine oxides was reported. H-Phosphinates and H-phosphine oxides react stereospecifically with CuCl2 to produce the corresponding optically active Z1Z2P(O)Cl with retention of configuration at the phosphorus center. Optically active Z1Z2P(O)Cl reacts easily with a variety of nucleophiles to produce other chiral organophosphorus acid derivatives with inversion of configuration at phosphorus

secondary phosphine oxides with amines and alcohols proceeds highly stereospecifically to give the corresponding coupling products with inversion of configuration at the phosphorus center under the Atherton−Todd reaction conditions. This finding leads to the establishment of a general and efficient method for the synthesis of a variety of opticallyactive organophosphorus acid derivatives from the easily
