Despite their promising properties, hypervalent bromine(III) reagents remain underexplored due to their low stability and difficult preparation. A fresh approach involves chelation-stabilized bromine(III) species which are conveniently prepared by electro-oxidation of parent bromoarenes. The intrinsic Br(III) reactivity can be unlocked in the presence of acids. In this mechanistic study, electrochemical synthesis, redox properties, and chemical reactivity aspects of chelation-stabilized hypervalent bromine(III) species are disclosed.
