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 convenient synthesis 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。
