The excellent reactivity of diaryliodonium salts has primarily been attributed to the efficient departure of the iodoarene unit, facilitating a variety of arylation reactions. However, one equivalent of iodoarene as a side-product is a chemical waste in these reactions, which was criticized by chemists for hindering its popularity. Recently, the development of synthetic methodology that preserve the aryl iodine moiety received increasing attention. Oxidative rearrangement reactions involving aryliodonium reagents have significantly addressed the atom-economic issue, thereby broadening the reaction scope. The resulting intricate aryliodine products are viewed as valuable synthons for the synthesis of natural products, pharmaceutical intermediates and other fine chemicals.

通过芳基碘鎓重排反应合成多功能芳基碘合成子


二芳基碘鎓盐优异的反应活性主要归因于碘芳烃单元的有效脱离，促进了各种芳基化反应。然而，这些反应中的副产物碘芳烃是一种化学废物，化学家批评其阻碍了其普及。最近，保留芳基碘部分的合成方法的发展受到越来越多的关注。涉及芳基碘鎓试剂的氧化重排反应显着解决了原子经济问题，从而拓宽了反应范围。由此产生的复杂芳基碘产品被视为合成天然产物、药物中间体和其他精细化学品的有价值的合成子。
