  摘要：

  本发明提供了一种合成8‑(硝基甲基)喹啉类化合物的方法：以8‑甲基喹啉类化合物为原料，与催化剂和硝化试剂加入有机溶剂中，密闭加热至80‑130℃反应，TLC跟踪至反应结束后，反应液后处理制得式II所示的8‑(硝基甲基)喹啉类化合物。本发明的硝化方法具有硝化位置专一性的优点，只在甲基上硝化，而没有苯环上硝化产物的生成，反应过程安全环保、底物适应性好，各种取代基都可以实现甲基硝化；直接以8‑甲基喹啉为原料，反应步骤简单，是一种合成各种含取代基的8‑(硝基甲基)喹啉类化合物的新路线。

  powerful catalytic system for hydroxylation of (hetero)aryl halides. A wide range of (hetero)aryl chlorides bearing either electron-donating or -withdrawing groups proceeded well at 130 °C, delivering the corresponding phenols and hydroxylated heteroarenes in good to excellent yields. When more reactive (hetero)aryl bromides and iodides were employed, the hydroxylation reactions completed at relatively

  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
