文摘

A selection of new η⁸-permethylpentalene zirconium and hafnium complexes are reported. The first d-block metal bis(permethylpentalene) sandwich complexes, (Pn*₂M ; Pn* = C₈Me₆ ; M = Zr, Hf) have been synthesized and structurally characterized. The bis-allyl species Pn*M(C₃H₅)₂ (M = Zr, Hf) have been synthesized; these complexes are fluxional in solution and react with CO₂ to give the double-insertion product Pn*M(κ²-O₂CCH₂CHCH₂)₂ (M = Zr, Hf). We also report monometallic, bimetallic, and polymeric σ-bonded alkyl derivatives such as (Pn*Zr)₂(μ-CH₂)(μ-Me)₂, [Pn*Hf(CH₂Ph)₃][Li(1,4-dioxane)₄], and [Pn*ZrPh(μ-Ph)₂Li(μ-1,4-dioxane)]_n.
