The present invention relates to a process for preparing 1,3-disilacyclotutanes by pyrolyzing alkoxytrisilaalkaness at a temperature of from 400.degree. C. to 800.degree. C. at the atmospheric pressure or under the vacuum. This is a new synthetic route of 1,3-disilacyclobutanes which employs readily available starting materials without using alkaline metals or magnesium, affords very good yields, produces very clean product mixtures separable by distillation, and tolerates functionality on silicon.
本发明涉及一种制备1,3-二硅杂环丁烷的方法,该方法通过将烷氧基三硅烷烷在大气压或真空下在400℃至800℃的温度下热解而得到。这是一种新的合成路线,使用易得的起始材料而不使用碱金属或镁,产率非常高,产生非常干净的产品混合物,可通过蒸馏分离,并且对硅上的功能团容忍度高。
