Abstract

A convenient procedure for the preparation of -iodo ketones by oxidative iodination of ketones using iodine and m-iodosylbenzoic acid as a recyclable hypervalent iodine oxidant is reported. Various ketones and -dicarbonyl compounds can be iodinated by this reagent system under mild conditions affording the respective -iodo-substituted carbonyl compounds in excellent yields. The final products of iodination are conveniently separated from byproducts by simple treatment with anionic exchange resin Amberlite IRA 900 HCO3 - and are isolated with good purity after evaporation of the solvent. The reduced form of the hypervalent iodine oxidant, m-iodobenzoic acid, can be recovered in 91-95% yield from the Amberlite resin by treatment with aqueous hydrochloric acid followed by extraction with ethyl acetate.
