Mechanochemical conditions have been applied to an iridium(III)‐catalyzed C−H bond amidation process for the first time. In the absence of solvent, the mechanochemical activation enables the formation of an iridium species that catalyzes the ortho‐selective amidation of benzamides with sulfonyl azides as the nitrogen source. As the reaction proceeds in the absence of organic solvents without external
机械化学条件首次应用于铱(III)催化的CH键酰胺化过程。在没有溶剂的情况下,机械化学活化能够形成铱物种,该物种催化以磺酰叠氮化物为氮源的苯甲酰胺的邻位选择性酰胺化。由于在没有有机溶剂的情况下无需外部加热即可进行反应,并且可以在较短的反应时间内以优异的收率获得所需的产物,因此该方法可替代常规的基于溶剂的标准方法,是一种功能强大,快速且对环境无害的选择。
