Tetramethylammonium hydroxide → Tetramethylammonium pentafluorobenzenesulfonate

Participants

Reaction Steps

Pentafluorobenzenesulfonyl chloride (25 g) was dissolved in 100 ml of methanol with ice-cooling, and 100 g of a 25% aqueous solution of tetramethylammonium hydroxide was gradually added thereto. The reaction mixture was stirred at room temperature for 3 hours, thereby a solution of a pentafluorobenzenesulfonic acid tetramethylammonium salt was obtained. This solution was used for salt exchange of a sulfonium salt and an iodonium salt.
