实验步骤: 15.246 g (0.10 mol) sodium chlorodifluoroacetate, is dissolved to 100 mL Et2O and cooled to −70° C. 19.7 mL (0.10 mol, 19.872 g) chlorotriethoxysilane in Et2O (50 mL) was added dropwise to reaction solution. The solution was stirred for over night allowing it to warm up to room temperature. NaCl is removed by filtration and solution evaporated to dryness to result clear colourless liquid, chlorodifluoroacetic acid, triethoxysilyl ester. to warm up to room temperature NaCl is removed by filtration and solution evaporated to dryness

实验步骤: 6.123 g (0.0651 mol) sodium acrylate is dissolved to 25 mL THF and cooled to −70° C. 12.8 mL (0.0651 mol, 12.938 g) chlorotriethoxysilane in THF (15 mL) is added dropwise to reaction solution. The solution is stirred for over night allowing it to warm up to room temperature. NaCl is removed by filtration and solution evaporated to dryness to result clear liquid, acryltriethoxysilane. to warm up to room temperature NaCl is removed by filtration and solution evaporated to dryness

实验步骤: Chlorotriethoxysilane (2.0 mL, 10 mmol, 1.0 equiv) was added to a stirred solution of 0.5M ethynylmagnesium bromide (20 mL, 10 mmol, 1.0 equiv) in tetrahydrofuran (10 mL) at −78° C. The resulting heterogeneous light brown mixture was immediately warmed to 23° C. and stirred for 1 h. The resulting homogeneous light brown solution was heated to 50° C. and stirred for 4 h. The cooled reaction mixture was concentrated under vacuum. The resulting tan powder was slurried in hexane (50 mL), vacuum filtered, and rinsed with additional hexane (3×25 mL). The filtrates were dried over magnesium sulfate, gravity filtered, and concentrated under vacuum to provide the title compound as a pale yellow oil (1.5 g, 80% yield): IR (thin film) 3252 (w), 2976 (s), 2929 (m), 2913 (w), 2890 (m), 2046 (m) cm−1; 1H NMR (400 MHz, CDCl3) δ 3.90 (q, J=7 Hz, 6H), 2.35 (s, 1H), 1.23 (t, J=7 Hz, 9H). The resulting homogeneous light brown solution was heated to 50° C. stirred for 4 h The cooled reaction mixture was concentrated under vacuum vacuum filtered rinsed with additional hexane (3×25 mL) The filtrates were dried over magnesium sulfate, gravity filtered concentrated under vacuum
