Procedure

25 Grams (93.8 mmols) of pentafluorobenzenesulfonyl fluoride was charged in a flask, and 13.0 g (93.8 mmols) of potassium carbonate and 100 ml of water were added under cooling with ice, followed by stirring at room temperature for 9 hours. Then, 1.3 g (9.4 mmols) of potassium carbonate was further added and the mixture was stirred at 60° C. for 1 hour. A white solid produced was filtered off and purified by recrystallization with water. The resulting white solid was subjected to 19F-NMR measurement and it was confirmed that the resulting white solid was potassium pentafluorobenzenesulfonate (c).
