: Iodine(III)-based reagents has been broadly used in oxidative reactions for the structural functionalization with several functional groups. Among the more relevant and useful synthetic transformations using these hypervalent γ 3 -reagents, it can be found the fluorination, chlorination, bromination as well as the iodination protocols. Herein, we present some of the most representatives 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.
