METHOD FOR THE SYNTHESIS OF PERFLUOROSULPHONAMIDES, PERFLUOROSULPHONAMIDES AND THEIR SALTS, AND A SULPHONATION REAGENT

摘要

The invention concerns a method of sulphonation characterised in that it consists in contacting a nucleophile whose nucleophilic atom is a nitrogen atom with a reagent comprising by successive or simultaneous addition: a heavy sulphonyl halide (i.e. whose atomic number is not less than that of chlorine), advantageously suphonyl chloride; and an organic base both not capable of alkylation and lipid soluble; and the organic part of said sulphonyl is perfluorinated on the carbon carried by the sulphur. The invention is applicable to organic synthesis.
