実験手順

In a 500 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 29.6 g (0.127 mole) of cyclopentyl triethoxysilane, 151.1 g (2.04 mole) of sec-butyl alcohol and 286.5 mg (4.21 m mole) of sodium ethoxide, which were then reacted with each other in an oil bath of 50° C. for 10 hours under stirring. Then, trimethylchlorosilane was added to neutralize the alkali. Then, 24.2 g (0.0931 mole) of sec-butoxy cyclopentyl diethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 73%
