In the presence of a palladium complex, 1,1-dimethyl-1-silacyclobutane reacts smoothly with dimethyl acetylenedicarboxylate to give 1,1-dimethyl-2,3-bis(methoxycarbonyl)-1-silacyclohex-2-ene in quantitative yield. Other silacyclobutanes react similarly with various acetylenes to give silacyclohexene derivatives.
在钯配合物的存在下,1,1-二甲基-1-硅杂环丁烷与乙炔二羧酸二甲酯平稳反应,以定量产率得到1,1-二甲基-2,3-双(甲氧基羰基)-1-硅杂环己-2-烯。其他硅杂环丁烷与各种乙炔类似地反应生成硅杂环己烯衍生物。
