Hypervalent organo-λ3-chloranes

Abstract

Hypervalent halogen species such as organoiodine(III and V) compounds have long been used as electrophiles/oxidants in organic synthesis, but recent years have seen the emergence of a new class of hypervalent halogen species, organobromine(III) and organochlorine(III) compounds (also termed organo-λ3bromanes and λ3-chloranes). In this review, we will cover recent developments in the synthesis and synthetic applications of functionalized λ3-chloranes.
