The intent of this account is to provide a focused overview of recent developments in aryl radical chemistry, especially extensions and applications of the Meerwein arylation and the Gomberg-Bachmann reaction. Although most of the reactions and methods described were discovered on the basis of earlier findings made by our group or logically depend on newly discovered reactivities or mechanistic principles, the rapid evolution of radical chemistry can nevertheless be traced back to the behavior of the natural product stephanosporin, which is capable of liberating 2-chloro-4-nitrophenol via an aryl radical intermediate. 1 Introduction to Aryl Radical Chemistry 2 Stephanosporin 3 Low-Temperature Radical Initiators That Generate Aryl Radicals 4 Alkene Functionalizations 4.1 Carboamination 4.1.1 Carbodiazenylation Reactions 4.1.2 Carbonitrosation Reactions 4.2 Carbooxygenation 4.3 Carbofluorination 4.4 Allylation and Vinylation 4.5 Reductive Arylation and Labelling with Fluorine-18 4.6 Cascade Reactions 5 Arene Functionalizations 5.1 Arylations with Aryldiazonium Salts 5.2 Arylations with Arylhydrazines 5.3 Acid-and Base-Induced Arylations 6 Summary and Outlook
