                                    A new method of synthesis of phosphonic and thiophosphonic chlorides is offered, based on treatment of acyclic and cyclic organylchlorophosphonium hexachlorophosphorates with dimethylformamide, dimethylacetamide, or dimethylthioacetamide. The method involves no formation of phosphoryl chloride and thiophosphoryl chloride, which facilitates isolation of the target products. The reactions of alkenylchlorophosphonium hexachlorophosphorates with amides and thioamides results in incorporation of the PCl6- anion into an insoluble chloroiminium salt which is easily separated by filtration. Removal of the solvent leaves almost. pure phosphonic or thiophosphonic chlorides.
