Procedure

To the same reactor as used in Example 1 were added 40.1 g (0.25 mole) of hexyldimethylsilanol, 160 g of 1,2-dichloroethane and 1.83 g (0.025 mole) of N,N-dimethylformamide, and 27.2 g (0.275 mole) of phosgene was introduced into the resulting mixture at a temperature of from 40° to 45° C. over 2 hours with stirring. After completion of the introduction, the same procedure as in Example 7 was carried out to obtain 40.7 g of hexyldimethylchlorosilane.
