Synthesis, structure and reactivity of highly functionalized η1-stibaallyliron complexes [(OC)2(η5-C5Me5)Fe–Sb(Cl)C(OSiMe3)
CPhR] (R = Ph, Me or c-C6H11)
Abstract
Insertion of one equivalent of CR1Ph] (R1 = c-C6H11 or Me). The remaining Sb–Si bond was readily cleaved by C2Cl6 to give complexes [(OC)2Cp*Fe–Sb(Cl)C(OSiMe3)
CR1Ph]. Treatment of the latter where R1 = Ph with LiSb(SiMe3)2·2.8thf, LiC
CPh, or LiC(N2)SiMe3 resulted in the formation of compounds [(OC)2Cp*Fe–Sb(R)C(OSiMe3)
CPh2 [R = Sb(SiMe3)2, C
CPh or C(N2)SiMe3]. The new compounds were characterized by elemental analyses and
CPh2] was elucidated by a single crystal X-ray diffraction analysis.
