Abstract

The reactions of hydrosilane and/or alkyne as well as isonitriles with rhodium and rhodium cobalt mixed metal carbonyl clusters, e.g., Rh₄(CO)₁₂ and Co₂Rh₂(CO)₁₂, are studied. Novel mixed metal complexes, e.g., CoRh(CO)₅ (HC≡CBuⁿ), (R₃Si)₂Rh(CO)_nCo(CO)₄, Rh(R-N≡C)₄Co(CO)₄, Co₂Rh₂(CO)₁₀(HC≡CR), and Co₂Rh₂(CO)₉(HC≡CBuⁿ), are synthesized and identified. The catalytic activities of these rhodium and rhodium-cobalt mixed metal complexes are examined in hydrosilyation, silylformylation, and novel silylcarbocyclization reactions. Possible mechanisms for these reactions are proposed and discussed.
