Hypervalent iodine heterocycles represent one of the important classes of hypervalent iodine reagents with many applications in organic synthesis. This paper reports a simple and convenientsynthesis of benziodazolones by the reaction of readily available iodobenzamides with m-chloroperoxybenzoic acid in acetonitrile at room temperature. The structure of one of these new iodine heterocycles was confirmed
高价碘杂环代表了一类重要的高价碘试剂,在有机合成中有许多应用。本文通过容易获得的iodobenzamides与反应报告benziodazolones的简单且方便的合成米氯过氧苯甲酸在室温下,在乙腈中。这些新的碘杂环之一的结构通过 X 射线分析得到证实。与 PPh 3和吡啶结合,这些苯并咪唑酮可以顺利地与醇或胺反应,分别生成相应的 3-氯苯甲酸酯或酰胺。发现在该酯化反应中,新型苯并碘酮试剂比类似的苯并恶酮试剂反应更有效。
