Versuchsvorschrift
The procedure of Example 1 was followed using α-toluenesulfonyl fluoride (2.0 g, 11.5 mmol) in dry tetrahydrofuran (15 mL), potassium trimethylsilanolate (1.48 g, 11.5 mmol) and dry tetrahydrofuran (45 mL), and 2 h of heating at reflux. Potassium α-toluenesulfonate (1.41 g, 58% yield) was isolated as a white solid: 1H NMR (D2O) δ 4.1 (s, CH2, 2H), 7.4 ppm (s, Ar--H's, 5H).
