Procedure

36.39 g of 11,11-dimethoxyundec-1-ene (7) obtained above in the first stage (170 mmol) are dissolved in 31.025 g of 97% triethoxysilane (34.86 ml, 183 mmol, 1.08 eq.). Subsequently, 0.424 g (0.45 mmol, 0.0026 eq.) of Karstedt catalyst is added very slowly. After stirring at ambient temperature for 3 hours, the crude reaction product is purified by distillation to give 41.88 g of a colorless liquid (yield of 65%) melting at a temperature of 115°-120° C. (at a pressure of 10−2 mm of mercury).
