This invention pertains to novel processes for preparing phosphorus derivatives of aminothiomethylcarbamates using as intermediates corresponding phosphorus derivatives of aminothiocarbamic halides. The carbamates are useful as pesticides against insects, mites, and nematodes. Two processes for preparing the corresponding intermediates are described. One preparation generally reacts an appropriate N-chlorothiophosphoramide with N-methylcarbamoyl halide. The other preparation generally reacts an N-chlorothiomethylcarbamoyl halide with an appropriate phosphoramide. The intermediate will react with various alcohols to produce the desired carbamates in the process of the invention.
