  使用 N-溴和 N-氯代琥珀酰亚胺作为双功能试剂的机械化学级联 C-N 交叉偶联和卤化

  摘要：

  化学转化替代能源的探索引起了化学家的极大兴趣，机械化学就是其中之一。在此，我们报告了使用N-溴代琥珀酰亚胺 (NBS) 和N-氯代琥珀酰亚胺 (NCS) 作为双功能试剂用于级联 C-N 键形成和随后的卤化反应。在无溶剂机械化学（球磨）条件下，从N合成多种菲啶酮衍生物-甲氧基-[1,1'-联苯]-2-甲酰胺完成。在反应过程中，NBS 和 NCS 首先辅助氧化 C-N 偶联反应，随后促进卤化反应。因此，NBS 和 NCS 的作用被确立为双功能。总体而言，实现了各种溴代和氯代菲啶酮衍生物的温和、无溶剂、方便、一锅法和直接合成。

  摘要：

  公开了一种操作简单的方案，以促进直接从联芳基羧酸进入苯并-3,4-香豆素，而无需底物预官能化。作为经典内酯化策略的补充，这种分离依赖于光活化的（-）-核黄素（维生素B 2）的氧化能力，可通过光诱导的单电子转移生成杂环核。总的来说，催化剂的廉价性质，易于实施以及不存在外部金属添加剂，都令人信服地赞同将简单的维生素掺入现代催化剂中。
