Procedure: In a 100 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 25.0 g (0.131 mole) of cyclopentyl trimethoxysilane, 9.74 g (0.131 mole) of tert.-butyl alcohol and 20 mg (0.18 m mole) of potassium tert.-butoxide, which were then reacted with each other by heating under stirring in an oil both of 80° C. for 10 hours. After cooled, ammonium chloride was added to neutralize the alkali. Then, tert.-butoxy cyclopentyl dimethoxysilane of 6.25 g (0.0269 mole) was obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 21%. In a 100 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were then reacted with each other by heating After cooled

Procedure: In a 100 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 7.7 g (0.0404 mole) of cyclopentyl trimethoxysilane, 35.7 g (0.405 mole) of 3-hydroxy tetrahydrofurane and 53.0 mg (0.98 m mole) of sodium methoxide, which were then reacted with each other in an oil bath of 80° C. for 2 hours under stirring. After cooled, trimethylchlorosilane was added to neutralize the alkali. Then, 5.37 g (0.0218 mole) of cyclopentyl dimethoxy oxa-3-cyclopentyloxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 54%. In a 100 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were then reacted with each other in an oil bath of 80° C. for 2 hours After cooled
