A simple, one-step procedure for the synthesis of diaryliodonium salts is described. It is shown that the electrochemical oxidation of an aryl iodide at a carbon felt anode in acetic acid/25% acetic anhydride/5% sulfuric acid in the presence of an arene leads to a diaryliodonium salt in good yield. The method allows the preparation of unsymmetrical, as well as symmetrical diaryliodonium salts. (C) 2000 Elsevier Science Ltd. All rights reserved.

An ammonium hydroxyfluoroalkanesulfinate is obtained by using an organic base while sulfinating a bromofluoroalcohol with a sulfinating agent. An ammonium hydroxyfluoroalkanesulfonate is obtained by oxidizing the ammonium hydroxyfluoroalkanesulfinate. An onium fluoroalkanesulfonate is obtained by converting the ammonium hydroxyfluoroalkanesulfonate into an onium salt through esterification. This onium fluoroalkanesulfonate is useful as a photoacid generator in chemically amplified resists and the like.
