Aromatic amines belong to a highly important class of organic compounds which are found in various natural products, functional materials, and pharmaceutical agents. Their prevalence has sparked continuing interest in the development of highly efficient and environmentally benign synthetic strategies for the construction of these compounds. Cross-dehydrogenative coupling reactions between two unmodified C(X)–H bonds have recently emerged as a versatile and powerful strategy for the fabrication of new C(X)–C(X) bonds. In this context, several procedures have been reported for the synthesis of aromatic amines through the direct amination of aromatic C–H bonds with free amines. This review highlights recent advances and progress in this appealing research arena, with special emphasis on the mechanistic features of the reactions.

芳香胺属于在各种天然产物，功能材料和药剂中发现的高度重要的有机化合物类别。它们的普遍性激发了人们对开发用于构建这些化合物的高效，环境友好的合成策略的兴趣。最近，两个未修饰的C（X）–H键之间的交叉脱氢偶联反应已成为制造新C（X）–C（X）键的一种通用而强大的策略。在这种情况下，已经报道了几种通过将芳族CH键与游离胺直接胺化来合成芳族胺的方法。这篇综述着重介绍了这个吸引人的研究领域的最新进展和进展，特别强调了反应的机理特征。
