Process for preparing aromatic sulfonyl halogenides |
| abstract |
Preparation of aromatic sulfohalides by reacting an aqueous hydrohalic acid solution of an aromatic diazonium halide with sulfur dioxide, in which a) the aqueous solution containing the hydrogen halide of a diazonium salt, which is derived from the corresponding aromatic amine and the halogen of the desired sulfohalide, in the presence of a reacting inert or only miscible inert organic solvent with sulfur dioxide, b) the diazonium salt is decomposed simultaneously or subsequently by means of a diazonium salt decomposition catalyst and c) the reaction mixture obtained or its organic phase is treated with an oxidizing agent after removal of the aqueous phase. |
