This invention pertains to novel phosphorus derivatives of aminothiocarbamic halides and processes for their preparation. The carbamic halides are readily prepared by two general procedures. In one procedure an appropriate N-(chlorothio)phosphorus amide reactant is readily prepared by reacting the corresponding phosphorus amide with sulfur dichloride which reactant will react with N-methylcarbamoyl halide so as to produce the corresponding object compounds of this invention. In a different procedure the same compounds that are the object of this invention are prepared by reacting an appropriate corresponding phosphorus amide with an N-chlorothiomethylcarbamoyl halide reactant which reactant is readily prepared by reacting N-methylcarbamoyl halide with sulfur chloride. The novel compounds of this invention are intermediates for the preparation of pesticides.
