Versuchsvorschrift
32.9 g (91.4 mmol) of compound (C) was added to a 1 N solution of sodium carbonate in ethanol and the mixture was heated at 70° to 80° C. for 3 h to conduct the hydrolysis. 27.7 g (87.1 mmol) of 3-hydroxypropyltriphenylsilane (D) was thus obtained (yield: 95.4%). 250 ml of dry benzene was placed in a flask after replacing air in the flask with a dry inert gas (argon). 5.0 g (15.7 mmol) of compound (D) and 1.9 g of triethylamine were dissolved therein. 50 ml of a solution of 1.6 g (17.7 mmol) of acryloyl chloride in benzene was added slowly thereto. After the completion of the addition, the mixture was stirred at room temperature for 6 h. The reaction solution was washed with a 0.5 N hydrochloric acid, water, a 1 N sodium carbonate solution and water successively and then dried over magnesium sulfate. Benzene was distilled off and the residue was purified according to column chromatography (silica gel/benzene) to obtain 5.1 g (13.7 mmol) of 3-acryloyloxypropyltriphenylsilane in the form of white crystals (yield: 87.3%).
