実験手順

In a 100 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 10.1 g (0.0531 mole) of cyclopentyl trimethoxysilane, 30.6 g (0.347 mole) of tert-amyl alcohol and 86.4 mg (1.6 m mole) of sodium methoxide, which were then reacted with each other in an oil bath of 105° C. for 4 hours under stirring. Then, trimethylchlorosilane was added to neutralize the alkali. Then, 10.7 g (0.0434 mole) of tert-amyloxy cyclopentyl dimethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 82%.
