| 摘要 |
This invention pertains to novel processes for preparing phosphorus derivatives of aminothiomethylcarbamates known to be useful as pesticides. The processes use products prepared by a novel method which reacts disulfides of various amides of phosphoric acids with chlorine or bromine. Such sulfenyl halide products are advantageous and obtained in unexpected yields. Therefore, the method is also unobvious. When the novel sulfenyl bromides of this invention are intermediates unexpected yields of pesticides are obtained.
