Abstract

The Cp*Si⁺ cation acts as a stoichiometric source of silicon in the reaction with the disilenide Tip₂Si=Si(Tip)Li (Tip = 2,4,6-ⁱPr₃C₆H₂) affording known neutral unsaturated silicon clusters. It thereby provides a conceptually different approach to this novel class of compounds. The proposed mechanism involves a Cp*-substituted cyclotrisilene in which Cp*⁻ acts as a leaving group upon single electron reduction or in a nucleophilic substitution step.
