IBX—New Reactions with an Old Reagent

Abstract

A single-electron transfer (SET) is the key step in new reactions using the hypervalent iodine compound 2-iodoxybenzoic acid (IBX) 1 as a reagent. Efficient oxidations of alcohols, oxidation of the benzylic position, or introduction of α,β-double bonds into carbonyl compounds are other new applications of this reagent.
