Abstract

Starting out from [Cp^NNiI] (1), three new derivatives with polar σ(Ni-N) bonds of the type [Cp^NNiL] (Cp^N = [2-(N,N-dimethylamino)eth-1-yl]cyclopentadienyl; L = carbazolato, 3; maleimidato, 4; phthalimidato, 5) were synthesized by salt elimination. The new compounds were characterized by ¹H and ¹³C{¹H} NMR spectroscopy, elemental analysis, mass spectrometry and, in the case of 3 and 5, by single crystal X-ray diffraction studies. The presence of electron withdrawing groups R at the negatively polarized N-atom, allowing for charge delocalization strongly contribute to the stability of amido and/or imidato complexes at the Cp^NNi fragment.
