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

Abstract

AbstractHypervalent 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 Introduction2 Diaryl-λ3-bromanes3 Dialkyl-λ3-bromanes4 Dihetero-λ3-bromanes5 Alkenyl-λ3-bromanes6 Alkynyl-λ3-bromanes7 Conclusion and Prospects
