Abstract

In situ Grignard reactions of 1,8-(ClCH₂)₂C₁₀H₆ have yielded 2,3-dihydro-2,2-dimethyl-2-silaphenalene, which can be selectively momolithiated at the 1-position, and 1,8-(Me₃SiCH₂)₂C₁₀H₆, a compound readily dilithiated and subsequuently converted into the zirconium and hafnium metallacycles, meso-[M(η-C₅H₅)2(CHSiMe₃)₂C₁₀H₆]; the dilithium complex is converted into the complex [CHSiMe₃C(SiMe₃)C₁₀H₆][Li(tmeda)]₂ containing a silicon heterocycle dicarbanion and characterized as the substituted silaphenalene, the same product as the ClSiMe₃ adducts of momo-lithiated silaphenalene.
