25 g of pentafluorobenzenesulfonyl chloride was dissolved in 100 mL of methanol under ice cooling, and 100 q of a 25% tetramethylammonium hydroxide aqueous solution was gradually added to the solution. The mixture was stirred at room temperature for 3 hours to obtain a solution of pentafluorobenzenesulfonic acid tetramethylammonium salt. This solution was used for salt exchange with sulfonium salt and iodonium salt.
