  ethers, affording the corresponding aromatic cation radicals. Since then, hypervalent iodine(III) has been utilized as a selective and efficient SET oxidizing agent that enables a variety of direct C–H functionalizations of aromatic rings in electron-rich arenes under mild conditions. We have now extended the original method to work in a series of heteroaromatic compounds such as thiophenes, pyrroles,

  1994年，我们首先确定了苯基碘（III）双（三氟乙酸盐）（PIFA）对苯基醚的单电子转移（SET）氧化能力，提供了相应的芳族阳离子自由基。从那时起，高价碘（III）已被用作一种选择性和高效的SET氧化剂，可在温和条件下在富电子芳烃中实现芳环的各种直接C–H官能化。现在，我们已经将原始方法扩展为可用于一系列杂芳族化合物，例如噻吩，吡咯和吲哚。本文总结了自本世纪初以来的调查和结果。

  A series of electron-rich bipyrroles were prepared by the regioselective, phenyliodine(III) bis(trifluoroacetate) (PIFA) induced oxidative coupling of pyrroles in the presence of bromotrimethylsilane. Using pyrrole and 3,4-disubstituted pyrroles gave exclusively 2,2′-linked bipyrroles without the formation of other bipyrrole regioisomers. The 3-alkyl- or 3-aryl-substituted pyrroles gave unsymmetrical

  在溴代三甲基硅烷存在下，通过区域选择性的苯碘（III）双（三氟乙酸）（PIFA）诱导吡咯的氧化偶联制备了一系列富电子联吡咯。使用吡咯和 3,4-二取代吡咯仅得到 2,2'-连接的联吡咯，而不会形成其他联吡咯区域异构体。3-烷基或3-芳基取代的吡咯以高产率产生不对称的HT二聚体，作为对称HH二聚体上主要的可分离α-连接的联吡咯产物。N-取代基的性质显着影响反应的区域选择性，因此N-苯基-和N-苄基-取代的吡咯的区域控制联吡咯偶联得到2,3'-联吡咯。
