- N, N-dimethyl-N-phenyl-(N- fluorine two chlorine armor thio)-sulfonaide synthesis process
-
The invention discloses a process for synthesizing N,N-dimethyl-N-phenyl-(N-fluorodichloromethylmercapto)-sulfamide. The synthesis process comprises the following steps: by taking ferric fluoride as a fluoride, recrystallizing a toluene solution of fluorodichloromethylsulfuryl chloride and N,N-dimethyl-N'-phenyl sulfamide under a certain reaction conditions so as to prepare the N,N-dimethyl-N-phenyl-(N-fluorodichloromethylmercapto)-sulfamide. According to the synthesis process, an intermediate is synthesized, the utilization rate and yield of the intermediate can be improved in the intermediate preparation process, the residual substances are conveniently recycled after the reaction, the cost is greatly saved, and the environmental pollution is reduced. The ferric fluoride is taken as the fluoride in the intermediate synthesis process, so that the yield of the N,N-dimethyl-N-phenyl-(N-fluorodichloromethylmercapto)-sulfamide is improved, the influence on the environment is slight, and the problems that the N,N-dimethyl-N-phenyl-(N-fluorodichloromethylmercapto)-sulfamide is difficultly produced industrially because the raw material cost is high, the generated three industrial wastes have great damage to the environment and the yield is low and instable in the conventional method and the like are solved.
