A 6 - substituted -2 - trifluoromethylbenzene sulfonyl chloride method for the preparation of

The invention relates to a preparation method of 6-substituted-2-trifluoromethylbenzenesulfonyl chloride as a key intermediate of sulfonamide or sulfonylurea herbicides. The method comprises the following steps: 6-fluoro-2-trifluoromethylbenzenethioether is formed through fluorine displacement and sulfenyl group substitution of a raw material 2,3-dichlorobenzotrifluoride, chlorine oxidative chloridization or substitution of 6-fluoro-2-trifluoromethylbenzenethioether is carried out, and then chlorine oxidative chloridization of the finally obtained material is carried out to obtain the above product. The method has the advantages of easily available raw materials, simple process, high yield and low cost.
