Procedure

A solution of 11.0 g of 1,7-octadiene (Wako Pure Chemical Industries) and 26.9 g of diethoxymethylsilane (Shin-etsu Silicones) dissolved in toluene was incorporated with 0.05 mmols of a solution of Karstedt catalyst (U.S. Pat. No. 3,775,452) prepared from a chloroplatinate (Wako Pure Chemical Industries) and divinyl tetramethyldisiloxane (Gelest, Inc.), and the resulting mixture was stirred at 30° C. in a nitrogen atmosphere for 24 hours. The reaction effluent was purified by distillation, to obtain 1,8-bis(diethoxymethylsilyl)octane. Its structure was confirmed by NMR analysis.
