The intramolecular cyclization of silacyclooligoynes with [Mn (CO) <SUB>3</SUB> (Me-Cp)] produced a variety of silyl-substituted π-electron systems based on four- and five-membered rings. The silyl-substituted fulvene, dimethylenecyclobutene, [4] radialene derivatives afforded the corresponding dianion species by reduction with lithium metal in polar solvents, whereas the trimethylenecylopentene derivative gave a tetraanion. These anion species were isolated as dilithium or tetralithium salts of the corresponding π-electron systems. The structures both in crystals and in solution reveal that the silicon atoms attached to the π-electron systems play an important role for the stabilization of the resulting polyanions.
