  摘要：

  Cu(acac)2 和 N,N'-双(4-羟基-2,6-二甲基苯基)草酰胺 (BHMPO) 的组合为（杂）芳基卤化物的羟基化提供了强大的催化系统。各种带有给电子或吸电子基团的（杂）芳基氯化物在 130 °C 下均能很好地进行，以良好到极好的产率提供相应的酚类和羟基化杂芳烃。当使用反应性更强的（杂）芳基溴化物和碘化物时，羟基化反应在相对较低的温度（分别为 80 和 60 °C）下在低催化负载（0.5 mol% Cu）下完成。

  an isocyanate from the starting acyl azide via a Curtius rearrangement can trigger a [3 + 2] dipolar cycloaddition of polar N-oxide fragments to generate the aminated azine derivative. The applicability of this method is highlighted by the late-stage and sequential amination reactions of complex bioactive compounds, including quinidine and fasudil. Moreover, the direct transformation of aminated azines

  nitrogenation suffered from simple amidation/amination with limited atom‐economy and is mostly limited to C(sp2)−H substrates. In this work, anthranil was designed as a novel bifunctional aminating reagent for both C(sp2)−H and C(sp3)−H bonds under rhodium(III) catalysis, thus affording a nucleophilic aniline tethered to an electrophilic carbonyl. A tridendate rhodium(III) complex has been isolated as the
