Preparation of a N-ferrocenyl-amidinate complex was achieved by employing (TMEDA)Li[(CpFeC₅H₄)NC(Ph)NSiMe₃] (1) to prepare Cp*Zr[(CpFeC₅H₄)NC(Ph)NSiMe₃]Cl₂ (2). Complex 2 exhibited poor polymerization activity and thus a series of C-ferrocenyl bis(amidinate) complexes of the type M(L)₂Cl₂ (M = Zr, 4; M = Ti, 5; L = (CyNC(CpFeC₅H₄)NCy) were synthesized via reaction of ferrocenyl-amidine, H(L) and M(NMe₂)₂Cl₂ (M = Ti, Zr·2THF). Half sandwich mono(amidinate) complexes, Cp′ZrLCl₂ (Cp′ = Cp, 7; Cp′ = Cp*, 8), were prepared by the reaction of Cp′ZrCl₃ with Li(L) and subsequently alkylated to give M(L)₂Me₂ (M = Zr, 9; M = Ti, 11), CpZr(L)(CH₂Ph)₂ (12) and Cp*Zr(L)Me₂ (10) with the appropriate alkylating agent. Abstraction of a methyl group from 7 with B(C₆F₅)₃ and [Ph₃C][B(C₆F₅)₄] proceeded cleanly to give [{CyNC(CpFeC₅H₄)NCy}₂ZrMe][MeB(C₆F₅)₃] 13 and [{CyNC(CpFeC₅H₄)NCy}₂ZrMe][B(C₆F₅)₄] 14, respectively. Similarly, the analogous CpZr and Cp*Zr derivatives LZr{CyNC(CpFeC₅H₄)NCy}CH₂Ph] [PhCH₂B(C₆F₅)₃] L = Cp 15, Cp* 17 and [LZr{CyNC(CpFeC₅H₄)NCy}CH₂Ph][B(C₆F₅)₄] L = Cp 16, Cp* 18 were prepared. Cyclic voltammetry studies on the metal complexes containing ferrocenyl-amidinates reveal quasi reversible oxidation and reduction waves for the ferrocene/ferrocenium couple. The dichloride complexes (4–8) activated with MAO and dialkyl complexes (9,10) activated with B(C₆F₅)₃ and [Ph₃C][B(C₆F₅)₄] showed low ethylene polymerization activities.
