In the course of vacuum fractionation, N-(thio)phosphoryl-S-allylisothioureas are converted to N-(thio)phosphorylcarbodiimides.These latter were also obtained by elimination of H2S from N-(thio)phosphorylureas under conditions of Appel reaction or by reaction of (thio)phosphoric isothiocyanates with phosphinimine (Staudinger reaction), the latter method giving better results.Reactions of N-thiophosphorylthioureas with acetyl chloride or phenyl isothiocyanate yield mostly thiophosphorylated isothiocyanates, while reactions with chloroformamidine yield both isothiocyanates and carbodiimides.A synthesis is reported of 2-thiophosphoryliminoimidazolidines by reaction of thiophosphorylcarbodiimides with 2-bromoethylammonium bromide.
