Tetramethylammonium hydroxide → Tetramethylammonium pentafluorobenzenesulfonate

Participants

Reaction Steps

In 100 ml of methanol was dissolved 25 g of pentafluorobenzenesulfonyl chloride under cooling with ice, and 100 g of a 25% aqueous solution of tetramethylammonium hydroxide was gradually added thereto. The mixture was stirred for 3 hours at room temperature to obtain a solution of tetramethylammonium pentafluorobenzenesulfonate. The solution was used for salt exchange with a sulfonium salt or an iodonium salt.
