Procedure

An amount of 40.8 g of 2-chloroethyl-trichlorosilane is dissolved in 71.5 g of acetic acid anhydride, and the solution allowed to stand at room temperature for 21 hours in a closed vessel. The reaction product is concentrated in vacuo to obtain 44.6 g of 2-chloro-ethyl-tris-(acetyloxy)-silane, B.P.: 85° - 88°/0.1 Torr, nD20 = 1.6687. b) An amount of 26.9 g of 2-chloroethyl-tris-(acetyloxy)silane is dissolved in 40 ml of absolute benzene. To the solution are added at 50° - 55°, within 60 minutes, 10.8 g of benzyl alcohol in 20 ml of absolute benzene. Stirring is carried out for 41/2 hours at 50° - 55°. The reaction mixture is concentrated in vacuo, and 14.3 g of 2-chloroethyl-(benzyloxy-diacetyloxy)-silane are obtained, B.P.: 125 - 127°/0.001 Torr, nD20 = 1.4840. (Compound 1).
