A facile and clean procedure for preparation of -aminophosphonates via a rotary evaporator equipped with circulating water vacuum pumps

摘要

RE-CWVP (rotary evaporator equipped with a circulating water vacuum pump)-assisted synthesis is reported as an extremely efficient, facile, and clean procedure for the preparation of -aminophosphonates in organic synthesis and industrial processes. The title -aminophosphonates are obtained in good to satisfactory yields by the method and characterized by means of IR, 1H NMR, 31P NMR, 13C NMR, and mass spectrometry.
