Abstract

The new clusters HFeRu₂(μ-CX)(CO)₁₀ (X = OMe, NMe₂) have been prepared in low yield by metal fragment exchange. Hydrogenation of HFeRu₂(μ-COMe)(CO)₁₀ yields H₃FeRu₂(μ₃-COMe)(CO)₉. For X = NMe₂ reaction with PPh₃ gives HFeRu₂(μ-CNMe₂)(CO)₉(PPh₃) and HFeRu₂(μ-CNMe₂)(CO)₈(PPh₃)₂ with all substitutions on Ru. Kinetic studies of substitution by PPh₃ on HFe₃(μ-CNMe₂)(CO)₁₀ and on HFeRu₂(μ-CNMe₂)(CO)₁₀ found that the mechanism involves rate-determining CO dissociation. The order of relative rates for substitution, FeRu₂ > Fe₃ > Ru₃, suggests that CO dissociation occurs from Fe. The higher rate for the mixed-metal cluster is attributed to labilization of the Fe center by the Ru “ligand”.
