The thermolysis of linear and cyclic β-chloro-β'-ethylenesilicon compounds gives rise to two competitive reactions.Besides the classical β-elimination reaction, a new rearrangement reaction was observed, which depends on the Si-bonded R groups; it has not been noticed for the corresponding germanium compounds.To explain the results, we propose a mechanism involving a transient pentavalent silicon anion.
