friendly and efficient synthesis of primary phosphoramidates has been developed from benzyl/allyl/alkyl/propargyl halides in aqueous ethanol as a green reaction medium via in-situ formation of azide. The method is simple, metal free and high yielding at room temperature with wide substrate scope and functional group compatibility. The optimized protocol can be used for synthesis of phosphoramidate intermediates

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.
