METHOD FOR PREPARING OXYSULPHIDE AND FLUORINATED DERIVATIVES IN THE PRESENCE OF AN ORGANIC SOLVENT

摘要

The present invention concerns a method for preparing an oxysulphide and fluorinated derivative of formula (III) Ea-SO3R (III) that comprises bringing a compound of formula (II) Ea-SOOR (II) - Ea representing the fluorine atom or a group having 1 to 10 carbon atoms chosen from the fluoroalkyls, the perfluoroalkyls and the fluoroalkenyls; and - R representing hydrogen, a monovalent cation or an alkyl group; into contact, in the presence of a polar aprotic organic solvent, with an oxidising agent.
