Synthese und reaktivität von silicium-übergangsmetall-komplexen: XVIII. Trihydrosilylkomplexe des eisens: Darstellung und metallierung mit dicobaltoctacarbonyl

The reaction of the silyl complex Cp(CO)₂FeSiH₃ (1) with various donors under photochemical conditions leads to the formation of Cp(CO)(L)FeSiH₃ (2a-2c) and Cp(L)₂FeSiH₃ (3a, 3b) (L = MeNC, t-BuNC, Me₃P) via stepwise CO-substitution. 2a,2b are transformed by Co₂(CO)₈ to the complexes μ₂-Cp(CO)-(RNC)FeSiH] μ²-(CO)] Co₂(CO)₆ (3a,3b), the first complexes with a hydrogen substituted ferrio-silanediyl unit bridging two cobalt atoms.
