Iodosobenzene diacetate is an organic
reagent used as an oxidizing agent. This is suitable for cleaving glycols and
alpha-hydroxy ketones in ring opening and Mannich
reaction. Periodinane
(hypervalent iodine) is suited for the many oxidation and rearrangements
reactions including belows to prepare complex substances. Hypervalent iodine reagents are versatile synthetic tools which
have low
toxicity, enviromentally-friendly, mild reactivity with good yields, and ease of handling.
Some common hypervalent iodines are Di(acetoxyiodo)benzene [DIB],
(Bis(trifluroacetoxy)iodo)benzene [BTI], Iodosylbenzene [IOB],
((Hydroxy)(tosyloxy)iodo}benzene [HTI], 2-Iodoxybenzoic acid [IBX],
Dess-Martin Periodinane [DMP].
