The cluster anion [HRu 3(CO) 11] − as catalyst in hydroformylation, hydrogenation, silacarbonylation and hydrosilylation reactions of ethylene and propylene

Abstract

The trinuclear cluster anion [HRu 3(CO) 11] − was found to catalyze hydroformylation, hydrogenation, silacarbonylation and hydrosilylation reactions. Ethylene and propylene were hydroformylated with CO and H 2 to give the corresponding aldehydes; in the case of propylene a high yield of the unbranched butyraldehyde was obtained. Ethylene and propylene were hydrogenated at room temperature to the corresponding alkanes in almost quantitative yields. The formation of unsaturated silyl ethers was observed in the reactions of ethylene and propylene, respectively, with silanes and carbon monoxide. In the absence of CO, ethylene and propylene react with silanes to yield mainly silyl-substituted olefins. The catalytic turnover of these reactions was observed to be in the range of 50 – 400.
