Abstract
Abstract Novel synthesis of 1,3-disilacyclohexanes is achieved by silylation of bis(alkylthio)methyllithium with chloro(chloromethyl)dimethylsilane followed by ring closure with a base. The spiro-fused disilacyclohexane ring is shown to be structurally strain-free, like cyclohexane. A reaction mechanism is proposed involving a silacyclopropane intermediate whose electrophilic reactivity at silicon is supported by ab initio calculation.
