実験手順
The procedure of Example 1 was followed using perfluorohexanesulfonyl fluoride (7.9 g, 19.6 mmol), potassium trimethylsilanolate (2.52 g, 19.6 mmol), dry ether (150 mL), and a reaction time of nine days. Potassium perfluorohexanesulfonate (4.6 g, 53% yield) was isolated as a white solid: 19F NMR (methanol) δ -81.1 (m, --CF3 --, 3F), -114.4 (m, --CF2SO3⃝, 2F), -120.6 (m, --CF2CF2SO3⃝, 2F), -121.7 (m, --CF2 (CF2)2SO3⃝, 2F), -122.6 (m, CF3CF2CF2, 2F), 126.1 ppm (m, CF3CF2 --, 2F).
