In this work, we explore how adding a catalytic amount of an NC-type ligand improves ketone-directed ortho C−H arylation, whereas a full equivalent shuts down the transformation. Increased catalytic activity stems from the formation of a cyclometallated complex containing the NC-type ligand to provide an intermediate which accelerates the ortho-arylation of the ketone substrate.

2-(邻甲苯基)吡啶作为配体提高酮定向邻位芳基化的效率
在这项工作中,我们探索了如何添加催化量的 NC 型配体来改善酮定向的邻位C−H 芳基化,而完全等价的配体会阻止该转化。催化活性的增加源于含有NC型配体的环金属化络合物的形成,以提供加速酮底物邻位芳基化的中间体。
