The reaction of the molybdenum dimer [Mo2(CO)4(η-C5H5)2] with [M(CCR)(CO)2(η-C5H5)] (M = Ru or Fe, R = Me or Ph) has given different products dependent on the alkynylmetal. The ruthenium-containing starting materials gave the expected dimolybdenum alkynyl adducts as the only isolable materials in moderate yield. In contrast the iron alkynyls underwent Fe-C bond cleavage to give the simple known alkyne adducts [Mo2(μ-η2-HC2R)(CO) 4(η-C5H5)2] by a yet to be determined mechanism. The fluxional nature of the complex [MO2{Ru(μ-CCMe)(CO)2(η-C5H 5)}(CO)4(η-C5H5)2] was observed by solution NMR studies; the mechanism for equilibration of the molybdenum carbonyl groups at room temperature must involve disruption of the central Mo2C2 core.
