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) n Co(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.

The intramolecular trapping of a β-silylethenyl-Ni species by an alkyne moiety in 1,7-octadiyne and related systems, giving the corresponding carbocyclization product, was reported by Tamaoet al. (see K. Tamao, K. Kobayashi, and Y. Ito (1989).J. Am. Chem. Soc. 111, 6478).
