Processes for making phosphorus containing aminothiocarbamoyl halides

摘要

This invention pertains to novel phosphorus derivatives of aminothiocarbamic halides and prosesses for their preparation. The carbamic halides are readily prepared by two general procedures. In one procedure an appropriate N-(clorothio) 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-chlorothiemethylcarbamoyl 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.
