Photocatalytical and Photochemical Generation of Imidoyl Radicals: Synthetic Applications

Abstract In the last few decades, the development in the field of radical chemistry has gained great attention. The majority of these radical strategies mainly depend on the in situ generation of reactive radical species by employing radical initiators such as oxidants and metal salts or methods such as photocatalysis and electrochemistry etc. This review covers the literature on the generation of imidoyl radicals using photoredox catalysis. In the majority of the reactions, the spontaneity of the underlying SET transitions is correlated by the compiled redox potential data of the reacting species for a better understanding of the readers. Besides, the applications of these reactive imidoyl radicals to access a variety of heterocycles such as benzothiazoles, indoles, quinoxalines, phenanthridines, isoquinolines, pyridines, and amides are also addressed. magnified image
