実験手順

The reaction was carried out under the same condition as in Example 3, except that the same amount of t-butyl chloride was used as the hydrogen chloride source. A mixture of cyclopentyl chloride and t-butyl chloride having the mixing ratio of 1:2 was reacted with metallic silicon at 280° C. to give 30.1 g of reaction products. The reaction products contained 6.2 g (39.1%) of cyclopentyldichlorosilane and 0.3 g (1.6%) of cyclopentyltrichlorosilane. There were not starting materials unreacted. As other by-products, 3.7 g (58.4%) of cyclopentene, 2.9 g of trichlorosilane and unconfirmed materials were obtained.
