실험 절차

In a 100 ml three-neck flask provided with a magnetic stirrer were charged 10.3 g (0.0542 mole) of cyclopentyl trimethoxysilane, 40.3 g (0.543 mole) of sec-butyl alcohol and 33.7 mg (0.625 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, 10.6 g (0.0457 mole) of sec-butoxy cyclopentyl dimethoxysilane were obtained by vacuum distillation. Its structure was confirmed as in Example 1. FIGS. 1 and 2 are charts of 1H-NMR and IR, respectively. The yield was 84%.
