実験手順

The procedure of Example 1 was followed using ethyl perfluoropropionate (4.8 g, 25 mmol), potassium trimethylsilanolate (3.2 g, 25 mmol), and dry ether (150 mL). Potassium perfluoropropionate (4.7 g, 93% yield) was isolated as a white solid: 19F NMR (D2O) δ -79.5 (m, CF3, 3F), -117.5 (m, CF2, 2F). Anal. Calcd. for C3F5KO2 : C, 17.83; F, 47.00; K, 19.35. Found: C, 17.52; F, 46.83; K, 19.24.
