Abstract

The carbonylation of H₃Ru₃(μ₃-COMe)(CO)₉and hydrogenation of HRu₃(μ-COMe)(CO)₁₀were studied as a function of pressure up to 200 MPa. Carbonylation of the former cluster, forming the latter, is characterized by a volume of activation of +20 ± 2 cm³mol^-1, whereas the reverse reaction exhibits an activation volume of +9.6 ± 0.6 cm³mol^-1. These results are combined with predicted partial molar volumes to construct a volume profile for the overall process, from which it follows that both reaction steps follow a dissociative mechanism.
