  A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone® as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones

  通过使用NH 4 I作为碘的来源和Oxone®作为氧化剂，已经报道了一种简单，有效，温和和区域选择性的羰基化合物氧碘化方法。各种羰基化合物（如芳烷基酮，脂族酮（无环和环状）和β-酮酯）以中等至优异的收率发展为各自的α-单碘化产物。不对称脂族酮反应平稳，生成1-碘和3-碘酮的混合物，主要形成1-碘产物。

  Direct α-iodination of some ketones using iodine–cerium(IV) ammonium nitrate in acetic acid or methanol, gave the corresponding α-iodoketone in high yield. In the case of 2-pentanone, 4-methyl-2-pentanone, 2-hexanone, and 2-heptanone in methanol, the regioselective products were obtained.

• Aerobic oxidative α-iodination of carbonyl compounds using molecular iodine activated by a nitrate-based catalytic system
  作者：Rok Prebil、Stojan Stavber

  日期：2014.10

  The novel reaction system comprising air/NH4NO3(cat.)/I-2/H2SO4(cat.) is introduced as a simple, safe, cheap, efficient, and regioselective mediator for direct aerobic oxidative a-iodination of aryl, heteroaryl, alkyl, and cycloallcyl methyl ketones. The reaction system enabled the moderate to quantitative regioselective iodination of a large range of different methyl ketone derivatives including those bearing oxidizable heteroatom (S, N) substituents. Several activated aromatic compounds were also efficiently and selectively iodinated. The practical applicability of the presented reaction system was shown on 20 mmol scale under ambient pressure and 100% conversion of substrate was achieved. (C) 2014 Elsevier Ltd.
