The synthesis, spectroscopic and structural characterization of the novel nickel-gallium(I) heterocycle complex, [{Ga[N(Ar)C(H)]2}2Ni(mu-Cp)K(tmeda)(mu-Cp)K(mu-C7H8)0.5]infinity, Ar = C6H3Pri2-2,6, are reported. The compound is polymeric in the solid state and reacts with an N-heterocyclic carbene to give the neutral, square planar complex, trans-[Ni{C[N(Me)C(Me)]2}2{Ga[N(Ar)C(H)]2}2]. Analogies between the reactivities of the gallium(I) heterocycle and isoelectronic N-heterocyclic carbenes are discussed.
报道了新型镍-镓(I)杂环配合物[{Ga[N(Ar)C(H)]2}2Ni(μ-Cp)K(tmeda)(μ-Cp)K(μ-C7H8)0.5]∞(Ar = C6H3Pri2-2,6)的合成、光谱和结构表征。该化合物在固态下呈聚合物形式,并与N-杂环卡宾反应生成中性平面正方形配合物反式-[Ni{C[N(Me)C(Me)]2}2{Ga[N(Ar)C(H)]2}2]。讨论了镓(I)杂环与等电子N-杂环卡宾反应活性之间的相似性。
