The transformation of (hetero)arene cation radicals has become a powerful tool for the construction of highly functionalized (hetero)arenes. These (hetero)arene cation radicals could be generated under electrochemical, photochemical or chemical oxidation systems. The in situ generated (hetero)arene cation radicals can be attacked by various nucleophiles, such as (hetero)aromatics and anions, yielding structurally diverse molecules. Recently, a large number of impressive heteroarene modifications have been designed by this strategy. This review summarizes the advances in heteroarene modification via reactions of in situ formed (hetero)arene cation radicals, ranging from 2010 to 2020.

基于（杂）芳烃阳离子自由基的杂芳烃改性的最新进展。

（杂）芳烃阳离子自由基的转化已成为构建高度官能化（杂）芳烃的有力工具。这些（杂）芳烃阳离子可以在电化学，光化学或化学氧化系统下产生。原位生成的（杂）芳烃阳离子自由基会受到各种亲核试剂（如（杂）芳烃和阴离子）的攻击，从而产生结构上多样的分子。最近，通过这种策略已经设计了许多令人印象深刻的杂芳烃修饰。这篇综述总结了通过原位形成的（杂）芳烃阳离子自由基的反应在杂芳烃改性方面的进展，范围从2010年到2020年。
