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.

Abstract: The invention concerns a method for preparing an oxysulphide and fluorinated derivative, said method comprising the reacting, in the presence of an organic solvent, of: i) at least one compound of formula Ea-COOR (I), in which Ea represents the fluorine atom or a group having 1 to 10 carbon atoms chosen from fluoroalkyls, perfluoroalkyls and fluoroalkenyls and R represents hydrogen, a monovalent cation or an alkyl group, and ii) a sulphur oxide, said method being such that the initial molar ratio (sulphur oxide/compound of formula (I)) is less than 0.4 and the concentration of sulphur oxide dissolved in the reaction medium is kept constant for the entire duration of the reaction to a value of between 0.2% and 3% by weight by means of continually adding said sulphur oxide to the reaction medium.
