Abstract

In a method for the conversion of an aromatic sulphonyl fluoride to the corresponding sulphonyl chloride, the fluoride is heated with at least an equimolar amount of anhydrous aluminium chloride in a chloro-, bromo- and/ or fluoro-substituted hydrocarbon reaction medium having a boiling point of at least 50 DEG C.
