Abstract

AbstractCyclic diaryliodoniums are an important class of high‐valent aromatic iodine reagents for the synthesis of various axially chiral biaryls and biaryl compounds. Moreover, transition‐metal‐catalyzed annulation has been established for the construction of various heterocyclic rings and ladder‐type π‐conjugated polycyclic aromatic hydrocarbons with readily available cyclic diaryliodoniums as the starting materials. As halogen‐bonding donors, cyclic aryliodoniums have been explored as organocatalysts in a variety of organic reactions. In this review, the application progress of cyclic diaryliodoniums has been systematically outlined, which highlights recent developments in the application reactions of cyclic diaryliodoniums, including synthetic application, limitations and reaction mechanisms in representative cascade reactions to provide insights for the development prospects of cyclic diaryliodoniums.magnified image
