Vorschrift

A mixture of pentafluorobenzenesulfonyl chloride (25.0 g, 94 mmoles) and potassium hydroxide (86% purity, 12.3 g, 188 mmoles) was dissolved in 230 ml water and stirred at room temperature for 18 hours. The produced precipitate was filtered off and recrystallized from water (about 6 ml/g product). Colorless needles formed were filtered, washed with cool water and ethanol and dried in a vacuum oven for 24 hours to yield 22.1 g of potassium pentafluorobenzene sulfonate (82% yield).
