Abstract

Within the past decade, IBX (o-iodoxybenzoic acid) 1 has emerged as a powerful oxidant for several oxidative transformations. 2–5 Recently, IBX has been shown to enable conversions which proceed via oxygen transfer and expulsion of iodosobenzoic acid (IBA) using the oxide ligand of IBX as a nucleophile. 5,6 During our ongoing investigation of oxygenation reactions using polyvalent iodine compounds, 7 we found that IBX is an excellent reagent for the α- ...
