実験手順
5-phenyl-5H-dibenzo[b,d]thiophenium bromide (80.0 g, 234 mmol) and triethylammonium 1,1-difluoro-2-(methacryloyloxy)ethanesulfonate (78.5 g, 238 mmol) were dissolved in H2O (750 mL) and dichloromethane (750 mL) and stirred at r.t. for 18 h. The dichloromethane layer was separated and the aqueous phase washed with dichloromethane (3×500 mL). The combined organic layers were washed with water (3×1 L) and concentrated in vacuo to afford the title compound (109 g, 95%) as a white solid. 1H NMR (500 MHz, (CD3)2CO) δ: 8.56 (dd, J=7.5, 1 Hz, 2H), 8.42 (d, J=8 Hz, 2H), 8.05 (dt, J=8 Hz, 1 Hz, 2H), 7.77-7.87 (m, 5H), 7.69 (dt, J=8, 1 Hz, 2H), 6.14-6.16 (m, 1H), 5.66-5.69 (m, 1H), 4.75 (dd, J=15, 15 Hz, 2H), 1.93-1.94 (m, 3H).
