Polyfluoroarenes have been known for a long time, but they are most often used as fluorinated building blocks for the synthesis of aromatic compounds. At the same time, due to peculiar fluorine effect, they have unique properties that provide applications in various fields ranging from synthesis to materials science. This review summarizes advances in the radical chemistry of polyfluoroarenes, which have become possible mainly with the advent of photocatalysis. Transformations of the fluorinated ring via the C–F bond activation, as well as use of fluoroaryl fragments as activating groups and hydrogen atom transfer agents are discussed. The ability of fluoroarenes to serve as catalysts is also considred.

多氟芳基片段引发的自由基反应：光催化及其他

多氟芳烃早已为人所知，但它们最常用作合成芳香族化合物的氟化结构单元。同时，由于独特的氟效应，它们具有独特的性能，可在从合成到材料科学的各个领域中得到应用。这篇综述总结了多氟芳烃自由基化学的进展，这些进展主要是随着光催化的出现而成为可能的。讨论了通过C-F 键活化实现氟化环的转化，以及使用氟芳基片段作为活化基团和氢原子转移剂。还考虑了氟代芳烃作为催化剂的能力。
