Abstract
1. A new method has been found for the preparation of aryl-substituted 1,1-dialkylsilacyclopentanes (yield 30–75%). It consists in the reaction of a dialkyldichlorosilane and an excess of an arylethylene with alkali metal in an inert polar solvent. 2. The formation of silacyclopentanes is accompanied by the formation of the corresponding silahydrocarbon polymers having silicon atoms in the main chain (yield 70−25%). These are formed as the main products when alkali metals act on dichlorosilanes in presence of conjugated dienes such as piperylene. 3. The possible mechanism of the reaction of dichlorosilanes and arylethylenes with alkali metals is discussed.
