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.

The reactivity of anionic penta-coordinated silicon complexes 4-O)2>-Na+ 1 with nucleophilic reagents has been studied. 1 can be reduced to organosilanes RSiH3 by metallic hydrides.Reactions with an excess of Grignard or organolithium reagents (R'MgX or R'Li) gave tetraorganosilanes RSiR'3.When only two molar equivalents of Grignard reagents (R'MgX) or lithium reagents (R'Li) are added to complexs 1 functional silanes RR'2SiX can be prepared.

, (2008/06/13)
The present invention relates to new pentacoordinate silicon complexes, the process for their preparation and their application to the preparation of organosilanes. The pentacoordinate silicon complexes according to the invention correspond to the general formula I: STR1 in which: R denotes an alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, aralkynyl or alkylaryl radical in which the aliphatic fragments are linear, branched or cyclic and contain from 1 to 20 carbon atoms, A represents an alkali metal or alkaline earth metal, with the proviso however that A represents neither sodium nor potassium when R is a phenyl radical, and n=1 or 2.
