Abstract
Abstract Aryl halides are one of the most important chemical feedstocks in pharmaceuticals due to its easy accessibility, inexpensiveness, and widely utilized as aryl radical precursors in organic synthetic chemistry. Conventionally, the stoichiometric reagents such as AIBN/n‐Bu 3 SnH were used for generation of aryl radical from aryl halides, and suffered from requirement of toxic radical initiators, high temperature and thus, the development of simple, mild strategies for the generation of aryl radical from aryl halides are highly desirable. Recently, visible light mediated strategies received considerable attention, allowing the generation of aryl radical from aryl halides under mild reaction conditions. The present review described the recent breakthroughs and advancements in visible light mediated photocatalyst‐free C−B/C/O/P/Se/S bond formation of aryl halides.
