実験手順
The procedures of Example 2 were repeated with the exception that 10.0 g (0.0526 mole) of cyclopentyl trimethoxysilane, 85.1 mg (1.58 m mole) of sodium methoxide, and 52.7 g (0.526 mole) of cyclohexanol in place of sec-butyl alcohol were used and the reaction time was one and a half hours. Then, 11.3 g (0.0438 mole) of cyclohexyloxy cyclopentyl dimethoxysilane were obtained. Its structure was confirmed as in Example 1. FIGS. 3 and 4 are the charts of 1H-NMR and IR, respectively. The yield was 83%.
