  aromatic heterocyclic amines from cyclic amides. The most-reported methods for cyclic amide conversions to aromatic heterocyclic amines use an activating group, such as a halogen atom or a trifluoromethane sulfonyl group. However, subsequent elimination of activating groups during the amination process results in significant waste. This copper-catalyzed direct amination of cyclic amides in DMF forms aromatic

  在这里，我们描述了一种铜催化的方法，可以直接从环状酰胺中获得芳香族杂环胺。用于环酰胺转化为芳族杂环胺的最报道的方法使用活化基团，例如卤素原子或三氟甲烷磺酰基。但是，在胺化过程中随后消除活化基团导致大量浪费。铜催化的DMF中环状酰胺的直接胺化反应形成具有环境友好性且易于获得的试剂的芳香族杂环胺。已经提出该反应的可能的自由基机理。同时，N1原子的配位作用是该反应成功的关键，它为铜离子的C-O键活化和胺化提供了帮助。
