Synthesis and Reactivity of Silicon-Transition Metal Complexes, 31 - Metallosilanols and Metallosiloxanes, 6. - The First Hydroxysilanediyl-Bridged Binuclear Complexes: Selective Oxofunctionalization of the Silicon Bridge in Silanediyliron Complexes with DimethyldioxiraneOxygenation of [μ-(R)(H)Si][Fe(CO)2Cp]2 [R = Me (1a), pTol (1b)] with dimethyldioxirane (2) yields the μ-(hydroxysilanediyl)bisiron complexes [μ-(R)(HO)Si][Fe(CO)2Cp]2 [R = Me (3a), pTol (3b)]. In an analogous manner the cyclic complex (μ-OC)[μ-(Mes)(H)Si][Fe(CO)Cp]2(Fe-Fe) (6) obtained by photochemical reaction of Cp(OC)2Fe-Me (4) with MesSiH3, (5) is converted into (μ-OC)[μ-(Mes)(HO)Si][Fe(CO)Cp]2-(Fe-Fe) (7). 6 and 7 are obtained as a mixture of cis(Mes), cis(H or OH), and trans isomers.
