Synthetic use of poly[4-(diacetoxyiodo)styrene] for organic reactions

Poly[4-(diacetoxyiodo)styrene] is sufficiently reactive for the iodination of aromatics, the oxidative 1,2-aryl migration of alkyl aryl ketones, the a lpha-hydroxylation of ketones, and the oxidation of hydroquinones and sulfi des similarly to (diacetoxyiodo)benzene. Here, those reactions with poly[4- (diacetoxyiodo)styrene] are very useful because of the simple operation: t hus, filtration gives the crude products and recovered poly(4-iodostyrene) and then poly[4-(diacetoxyiodo)styrene] can be regenerated by oxidation of the recovered poly(4-iodostyrene) which are reused for the same reactions.
