Abstract

The reaction of [cis-{(η5-C5H3)2(CMe2)2}Ru2(κ2-4,4′-di-tert-butyl-2,2′-bipyridine)2(MeCN)2][OTf]2, 1, with H2 yields a μ-dihydrido complex, [cis-{(η5-C5H3)2(CMe2)2}Ru2(κ2-4,4′-di-tert-butyl-2,2′-bipyridine)2(μ-H)2][OTf]2, 2, in 79% yield. The reaction of 2 with Et3SiH affords a mono-μ-hydrido complex, cis-{(η5-C5H3)2(CMe2)2}Ru2(κ2-4,4′-di-tert-butyl-2,2′-bipyridine)2(μ-H)][OTf], 3. The reaction of either 2 or 3 (1-2 mol %) with C6H6 and Et3SiH results in the catalytic cleavage of the C-H bond in benzene along with the cleavage of the Si-Et bond to form PhEt2SiH (23-27% conversion) and C2H6. The reaction of 2 or 3 (1 mol %) with THF and Et3SiH results in the cleavage of the C-H bond in THF followed by the insertion of the SiEt2 group into the C-O bond, forming 2,2-diethyl-1-oxa-2-silacyclohexane (14% conversion) as one of the products.
