摘要：

Hydrogenation of the labile diruthenium di-mu-methylene complex, Cp2Ru2(mu-CH2)(2)(CO)(M2CN), produces a teranuclear mu(3)-methylidyne-mu(3)-hydride complex, Cp4Ru4(mu(3)-CH)(mu(3)-H)(mu-CO)(2), through methane-elimination and C-H oxidative addition. Treatment of the tetranuclear mu(3)-methylidyne-mu(3)-hydride complex with CO reverses the latter process to give a mixture of a mono-mu-methylene complex, Cp2Ru2(mu-CH2)(mu-CO)(CO)(2), and a carbonyl complex, Cp2Ru2(mu-CO)(2)(CO)(2).
