metal‐catalyzed ortho‐selective C(sp2)−H amidation of weakly coordinating aldehydes remains limited to precious metals such as Ir, Rh, Ru, etc. Herein, we put forward a novel report on ortho‐amidation of benzaldehydes employing user‐friendly dioxazolones under cost‐effective and air‐stable Cp*Co(III) catalysis. This catalytic transformation involves transient directing group strategy to enhance the ligating
过渡金属催化的邻选择性C(SP 2)-H的弱配位醛遗体局限于贵金属如铱,铑,钌等。这里酰胺化,提出了一种新颖的报告邻采用用户苯甲醛的酰胺化经济高效且空气稳定的Cp * Co(III)催化下的友好型二恶唑酮。这种催化转化涉及瞬态导向基团策略,以增强弱螯合醛的连接能力。
