Hypervalent Bromine(III) Compounds: Synthesis, Applications, Prospects

Abstract Hypervalent compounds play a prominent role in homogeneous oxidation catalysis. Despite the higher reactivity of hypervalent bromine compounds when compared to their isoelectronic iodine analogues, the corresponding λ3-bromanes are much less explored. This can be attributed to the discernible lack of convenient strategies for their synthesis. This short review highlights the available methods for the synthesis of various organo-λ3-bromanes, with a major focus on the recent developments and reactivities in the last few years. Additionally, limitations and future prospects of hypervalent bromine chemistry are discussed. 1 Introduction 2 Diaryl-λ3-bromanes 3 Dialkyl-λ3-bromanes 4 Dihetero-λ3-bromanes 5 Alkenyl-λ3-bromanes 6 Alkynyl-λ3-bromanes 7 Conclusion and Prospects
