Abstract: The oxygen transfer reagent, Me₃NO. 2H₂O and PhIO, can distinctly promote the coordinative hydrogenation of hex-l-ene, methyl methacrylate, and styrene catalyzed by heterometallic carbonyl clusters, (μ₃-S)RuCo₂(CO)₉ and (μ₃-Se)RuCo₂(CO)₉. The tetrahedron structure of the metal cluster catalyst was confirmed by the single-crystal X-ray diffraction. The tetrahedral skeleton of the catalyst keeps intact in catalytic process. For hex-1-ene in methanol solution, [Hex-1-ene]/[Cat.] = 200, [Me₃NO . 2H₂O]/[Cat.] = 4, p = 5.0-6.0 MPa, 60°C and 24 h are the best reaction conditions. A plausible mechanism of the promotion of the OTR is given.
