Abstract
Insertion of one equivalent of methyl(phenyl)ketene or cyclohexyl(phenyl)ketene into the Sb-Si bond of [FeCp*(CO)(2){Sb(SiMe3)(2)}] afforded eta (1)-stibaallyliron complexes [(OC)(2)(eta (5)-C5Me5)Fe-Sb(SiMe3)C(OSiMe3)=(CRPh)-Ph-1] (R-1=c-C6H11 or Me). The remaining Sb-Si bond was readily cleaved by C2Cl6 to give complexes [(OC)(2)Cp*Fe-Sb(Cl)C(OSiMe3)=(CRPh)-Ph-1]. Treatment of the latter where R-1=Ph with LiSb(SiMe3)(2).2.8thf, LiC=CPh, or LiC(N-2)SiMe3 resulted in the formation of compounds [(OC)(2)Cp*Fe-Sb(R)C(OSiMe3)=CPh2 [R=Sb(SiMe3)(2), C=CPh or C(N-2)SiMe3]. The new compounds were characterized by elemental analyses and spectra (IR, H-1, C-13, Si-29 NMR). The molecular structure of [(OC)(2)Cp*Fe-Sb(Cl)C(OSiMe3)=CPh2] was elucidated by a single crystal X-ray diffraction analysis.
