Procedure

In 100 ml of methanol was dissolved 25 g of pentafluorobenzenesulfonyl chloride under ice-cooling and 10 g of an aqueous solution of 25% tetramethylammonium hydroxide was slowly added to the solution. When the mixture was stirred for 3 hours at room temperature, a solution of a pentafluorobenzenesulfonic acid tetramethylammonium salt was obtained. The solution was used for the salt-exchange of a sulfonium salt and an iodonium salt.
