摘要： 硅杂环丁烷在有机硅化学中是一类非常重要的小分子环系化合物。由于硅杂环丁烷和环丁烷的环张力相似,因而显示出较高的反应活性。例如能与某些试剂作用,生成开环产物;在光解或热解条件下,产生具有Si=C结构的高活性中间体,可用以合成多种有机硅化合物。

Abstract: The 1-hydrocarbyl-1-Silacyclobutanes. HRSiCH2CH2CH2(R=H, Me, Et, i-Pr, Cyclo-hexyl, CH2Ph, Ph, p-MeC6H4, p-ClC6H4, w-MeC6H4m-ClCH4, Mesityl) were synthesized by the reaction of 1, 1-dichloro-1-silacyclobutane with LiAlH.,. The structure of 9 new compounds were characterized by 1HNMR, 1R and MS. The relationship between the Si-Hstretching vibration and the electronic and steric effects of substituents on the atom Si was discussed.

Key words: 1-hydrocarbyl-l-silacyclobutane. Synthesis, Si-H bond, Stretching vibration frequency, Monadic linear regression analysis
