Reaktionsschritte
In a 50 ml three-neck flask provided with a magnetic stirrer and a reflux condenser were charged 5.0 g (0.0262 mole) of cyclopentyl trimethoxysilane, 22.5 g (0.262 mole) of cyclopentyl alcohol and 18.6 mg (0.34 m mole) of sodium methoxide, which were then reacted with each other at room temperature for 2 hours under stirring. Then, trimethylchlorosilane was added to neutralize the alkali. Then, 5.4 g (0.0223 mole) of cyclopentyloxy cyclopentyl dimethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. The yield was 85%.
