Aryldiazonium Salts in Photoredox Catalysis – Recent Trends

Abstract Aryl diazonium salts are an important class of organic compounds that are now widely used as arylating agents in photoredox catalysis owing to their lower redox potential, broad substrate scope, and atom economy. They have successfully been used in many interesting organic transformations to introduce an aryl group. They serve as good alternatives for aryl halides and other aryl organometallic reagents primarily used as aryl group surrogates. New reactions using aryl diazonium salts are continually emerging, and in this review, we have highlighted some recent developments in photoredox arylations and their applications. magnified image
