Abstract
Hydrosilylation of methylenecyclopropane with dichloro(methyl)silane involves not only addition to the multiple bond, but also results in opening of the three-membered ring to form dichloro(cyclopropylmethyl)methylsilane and 1,4-bis(dichloromethylsilyl)butane. Dichloro(cycloalkylmethyl)methylsilanes were converted into the corresponding (cycloalkylmethyl)(diethynyl)methylsilanes by reaction with ethynylmagnesium bromide. The reaction of bis(bromomagnesioethynyl)(cyclobutylmethyl)methylsilane with dichlorodimethylsilane leads to cyclotetrasilaethyne framed with methyl and cyclobutyl groups. From 1,4-bis-[dichloro(methyl)silyl]butane and bis[(bromomagnesioethynyl)dimethylsilyl]ethyne or -ethene, 22-membered macrobicyclic highly unsaturated silahydrocarbons with an endocyclic tetramethylene bridge were synthesized.
