Treatment of 1-methylimidazol-2-yl lithium with Cp2Zr(Cl)CH3 (6) gave the corresponding methyl(1-methyl-2-imidazolyl)zirconocene complex 7. Treatment of 7 with B(C6F5)3 (8) led to selective methyl abstraction. The resulting (imidazolyl)zirconocene cation 9 dimerized under the reaction conditions to yield the dinuclear imidazolyl bridged bis(zirconocene) dication complex 10 that was structurally characterized by X-ray diffraction and by DFT calculations.
