The many synthetic possibilities that arise when using radical intermediates, in place of their polar counterparts, make contemporary radical chemistry research an exhilarating field. The introduction of photocatalysis has helped tame aryl radicals, leading to a resurgence of interest in their chemistry, and an expansion of viable coupling partners and attainable transformations. These methods are more selective and safer than classical approaches, and they utilize new radical precursors. Given the importance of sustainability in current organic synthesis and our interest in light-assisted metal-free transformations, this Review focuses on recent advances in the use of aryl radicals in photoinduced cross-couplings that do not rely on metals for the crucial bond-forming event, and it is structured according to the key step that the aryl radicals engage in.

使用自由基中间体代替极性中间体时出现的许多合成可能性，使当代自由基化学研究成为一个令人振奋的领域。光催化的引入有助于驯服芳基自由基，导致人们对它们的化学重新产生兴趣，并扩大了可行的偶联伙伴和可实现的转化。这些方法比传统方法更具选择性和安全性，并且它们利用新的自由基前体。鉴于可持续性在当前有机合成中的重要性以及我们对光辅助无金属转化的兴趣，本综述重点介绍了芳基自由基在光诱导交联中使用芳基自由基的最新进展，这些交联不依赖金属进行关键的键形成事件，并且它是根据芳基自由基参与的关键步骤构建的。
