Description
Summary:[Display omitted] A new, mild, efficient, and solvent-free microwave promoted synthesis of thiophosphoramidodichloridates and thiophosphoramidate diesters is described. The thionation reaction was accelerated with microwave irradiation using the combination of P 4S 10 and HMDO. The conversion of P O to P S by this method gave the desired product in higher yields and shorter reaction times as compared to conventional methods.
