Abstract

The reaction of the μ-methylidyne complex {[Cp(CO)Fe]₂(μ-CH)}⁺ PF₆^- (1) with C₆H₅(CH₃)₂SiLi and CuI produced [Cp(CO)Fe]₂(μ-CO)[μ-CHSi(CH₃)₂C₆H₅] (4). Reaction of p-tolyl carbyne complex {[Cp(CO)Fe]₂(μ-CO)(μ-CC₆H₄-p-CH₃)}⁺ BF₄^- (13) with nucleophiles NEt₄⁺HFe(CO)₄^- and Li(CH₃CuCN) gave μ-alkylidene complexes [Cp(CO)Fe]₂(μ-CO)(μ-CHC₆H₄-p-CH₃) (14) and [Cp(CO)Fe]₂-(μ-CO)[μ-C(CH₃)C₆H₄-p-CH₃] (15), respectively. Treatment of ethylidyne complex {[Cp(CO)Fe]₂(μ-CO)(μ-CCH₃)}⁺ BF₄^- (7) with Li(CH₃CuCN)·BF₃ produced μ-alkylidene complex [Cp(CO)Fe]₂(μ-CO)[μ-C(CH₃)₂] (17). Hydride abstraction from 17 by Ph₃C⁺ PF₆^- produced the μ-alkenyl complex {[Cp(CO)Fe]₂(μ-CO)[μ-η¹,η²-C-(CH₃)CH₂]}⁺ PF₆^- (18).
