Abstract

We report a rapid, efficient, economic, environmentally benign, and easy to scale-up method for the synthesis of phosphonamide derivatives using ultrasound irradiation, under catalyst and solvent-free conditions starting from the corresponding amine and phenyl phosphonic dichloride. The reaction was achieved in excellent isolated yield in a short reaction time at room temperature. The structures of the synthesized compounds are confirmed by elemental analysis as well as by IR and 1H, 13C, 31P NMR spectroscopic data and mass spectrometry.
