摘要：

[Cp(2)RuCl]PF6 reacts with benzylruthenocene in acetonitrile with a 1:1 stoichiometry to produce Cp(2)Ru and phenylruthenocenyl methylium cation. Similar hydride abstraction reactivity has also been observed with diruthenocenylmethane, ethylruthenocene, and benzylferrocene. The complexes [Cp(2)MX](+) (M = Ru, Os; X = Cl, Br, I) also react with leuco crystal violet and leuco malachite green to give the corresponding carbenium ions but do not exhibit any detectable reactivity with triphenylmethane, cycloheptatriene, or xanthene. On the basis of these observations, the PHR+ values for the [Cp(2)MX](+) species are estimated to be between +4.7 and +6.9.
