Vorschrift

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%.
