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-η12-C-(CH3)CH2]}+ PF6- (18).
