这篇专题文章总结了迄今为止在使用 C4 结合咪唑基作为一类新型过渡金属配体方面取得的进展。自从 2001 年发现这种不寻常的卡宾键合模式以来，已经开发出各种制备含有 C4 结合卡宾的配合物的合理途径。这些进展使得我们可以从基本角度和更应用的角度，特别是催化应用，研究这种新型配体对过渡金属中心的影响。在这段相对较短的时间内取得的有希望的结果证明了 C4 结合的亚咪唑基作为独特的卡宾配体诱导催化活性和介导前所未有的转化的潜力。
This feature article summarizes the progress achieved thus far in using C4-bound imidazolylidenes as a new class of ligands for transition metals. Since the discovery of this unusual carbene bonding mode in 2001, various rational routes towards complexes containing C4-bound carbenes have evolved. These advances allowed for studying the impact of this new type of ligand on the transition metal center, both from a fundamental point of view as well as from a more applied perspective, in particular for catalytic applications. The promising results accomplished in this relatively short period of time demonstrate the potential of C4-bound imidazolylidenes as unique carbene ligands for inducing catalytic activity and for mediating unprecedented transformations.
