Microwave-Assisted Solvent-Free Synthesis of Pseudohalophosphates

Abstract

A rapid, efficient, solvent-free, and catalyst-free procedure has been developed for the synthesis of pseudohalophosphates from phosphorochloridate and sodium (or potassium) pseudohalides under microwave irradiation. Diethyl, diisobutyl, and diphenyl phosphorazidates, phosphorocyanidates, and phosphor(isothiocyanidate)s 2a–2i were prepared in good yields under mild conditions.
