Oxidative Halogenation of Arenes, Olefins and Alkynes Mediated by Iodine(III) Reagents

Iodine(III)-based reagents have been broadly used in oxidative reactions for structural functionalization with several functional groups. Among the more relevant and useful synthetic transformations using these hypervalent λ³-reagents, the fluorination, chlorination, bromination, as well as the iodination protocols, can be found. Herein, we present some of the most representative oxidative halogenation procedures of arenes, olefins and alkynes dating from the oldest to the more recent advances in the area, highlighting the discovery and application of new iodine(III)-based halogenating species.
