2,3-Trisilacyclopent-4-ene generates silylene to give 1,2-disilacyclobut-3-ene on both photolysis and thermolysis. The silylene arises from either the central or the terminal silicon atom of the ring depending on the nature of substituents on the central silicon atom on photolysis, but the central silicon is ejected as silylene regiospecifically on thermolysis.
1,2,3-三硅杂环戊-4-烯通过光解和热解生成亚甲硅烷以得到1,2-二硅杂环丁-3-烯。根据光解时中心硅原子上取代基的性质,亚甲硅烷基来自环的中心硅原子或末端硅原子,但中心硅在热解时作为亚甲硅烷基区域特异性地排出。
