Resumo

The reactivity profile of IBX can be altered by complexation with various ligands (e.g. 1–4). A new complex, IBX⋅MPO, is a remarkably effective oxidant and allows the room-temperature dehydrogenation of carbonyl compounds, for example, the formation of cyclooctenones 6 and 7 from cyclooctanone 5. IBX = iodoxybenzoic acid; MPO = 4-methoxypyridine-N-oxide.
