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.
