Methods of producing sulfylimine compounds. The present invention relates to methods of producing a sulfylimine compound, such as n-cyano-s-methyl-s- [1- (6-trifluoromethyl-3-pyridinyl) ethyl] sulfylimine or another substituted sulfylimine compound. The method includes combining a sulfide compound, cyanamide, a hypochlorite compound, and a base, and oxidizing the sulfide compound to form the sulfylimine compound. The sulfide compound may include a 2-trifluoromethyl-5- (1-substituted) alkylthiopyridine compound. The base may include sodium hydroxide. A buffer, such as a phosphate buffer, may optionally be used in the reaction. |
