Abstract
The invention relates to a method for producing a fluorine- and sulphur-bearing compound of formula F—SO—R (I) or F—SO2—R (II), comprising the reaction, in the presence of water, of at least one salt providing a fluoride anion and at least one halgoenosulfoxide compound of formula X—SO—R′ (I0) from a halogenosulfonyl compound of formula X—SO2—R′ (II0), in which X is a halogen atom other than fluorine and R and R′ are each a group linked by a covalent bond to the sulphur atom, said bond linking the sulphur atom with a nitrogen atom. The invention also relates to a method for producing salts of a fluorine- and sulphur-bearing compound of formula F—SO—R (I) or F—SO2—R (II) which are advantageously used as electrolyte salts, as precursors of antistatic agents or as surfactant precursors.
