  Syntheses and Photochemically Induced Rearrangements of Tetrasilyl- and Trisilylgermyl Complexes of Iron:  (η⁵-C₅R₅)Fe(CO)₂(SiMe₂)₃EMe₂Ph (R = H, Me; E = Ge, Si)

  摘要：

  Oligosilyl and oligosilylgermyl complexes (eta(5)-C5R5)Fe(CO)(2)(SiMe2)(3)EMe2Ph (R = H (1), Me (2); E = Ge (a), Si (b)) have been synthesized, characterized, and photolyzed. All complexes isomerized cleanly to (eta(5)-C5R5)Fe(CO)(2)E(SiMe3)(2)(SiMe2Ph). Photolysis of a mixture of (eta(5)-C5Me5)Fe(CO)(2)(SiMe2)(3)GeMe2Ph (2a) and (eta(5)-C5H5)Fe(CO)(2)(SiMe2)(3)SiMe3 (1b) proved that the rearrangements occur via an intramolecular mechanism. Irradiation of 1 and 2 in the presence of HMPA resulted in the formation of (eta(5)-C5R5)Fe(CO)(=SiMe2. HMPA)(SiMe2-SiMe2EMe2Ph), indicating that silylene intermediates are key to the rearrangements. Attempts to use this new chemistry to perform the catalytic isomerization Me3GeSiMe2-SiMe2SiMe2H --> (Me3Si)(3)GeH resulted in high yields of (Me3Si)(3)GeSiMe2H. This product indicates the ability of (Me3Si)(3)GeH to intercept the Fe-silylene intermediates.
