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

Copper-catalyzed stereospecific oxidative dehydrocouplings of P(O)–H bonds with amines under air took place efficiently at room temperature to afford the corresponding amidophosphorus compounds in high yields. Mechanistic studies showed that this dehydrocoupling reaction proceeded stereospecifically with inversion of stereochemistry at phosphorus.
