A new method for the synthesis of the 1,3-disilacyclohexane skeleton is established involving silylation of a dithioacetal followed by ring closure with a base. The spiro-fused disilacyclohexane ring is shown to be structurally strain-free, like cyclohexane, on the basis of its X-ray analysis. The reaction mechanism involving a silacyclopropane intermediate is proposed.
