摘要:The present invention relates to a process and a reagent useful for the synthesis of sulphanilide which is perhalogenated on the carbon borne by the sulphur atom of the sulphanilide function. This persulphonylation process is characterized in that it comprises a step of placing a nucleophile, whose nucleophilic atom is a nitrogen, in contact with a reagent comprising, for successive or simultaneous addition, a heavy halide of sulphonyl, advantageously sulphonyl chloride, and an organic base comprising a trivalent atom from column V whose lone pair is conjugated directly or indirectly to a bond, and in that the organic part of the said sulphonyl is perhalogenated, advantageously perfluorinated, on the carbon borne by the sulphur. Application to the synthesis of intermediates for organic chemistry.
