Procedure

25 gof pentafluorobenzenesulfonyl chloride was dissolved in 100 ml of methanol under ice-cooling. Then 100 g of a 25% aqueous solution of tetramethylammonium hydroxide was slowly added thereto. By stirring at room temperature for 3 hours, a solution of tetramethylammonium pentafluorobenzenesulfonate was obtained. Thus solution was employed in salt exchange between sulfonium salt and iodonium salt.
