• Combining Eosin Y with Selectfluor: A Regioselective Brominating System for <i>Para</i>-Bromination of Aniline Derivatives
  作者：Binbin Huang、Yating Zhao、Chao Yang、Yuan Gao、Wujiong Xia

  DOI：10.1021/acs.orglett.7b01427

  日期：2017.7.21

  A mild, metal-free, and absolutely para-selective bromination of aniline derivatives has been developed in excellent yields, wherein the organic dye Eosin Y is employed as the bromine source in company with Selectfluor. Neither air nor moisture sensitive, this facile reaction proceeds smoothly at room temperature and completes within a short time. Mechanistic studies indicate a radical pathway; therefore

  已开发出具有优异收率的温和，无金属且绝对对位选择性的苯胺衍生物溴化物，其中有机染料曙红Y与Selectfluor一起用作溴源。无论是对空气还是对湿气都不敏感，这种反应很容易在室温下进行并在短时间内完成。机理研究表明了一条根本途径。因此，的原位产生的溴化试剂的存在，“Selectbrom”，是假设，可合理解释为独特区域选择性段的-bromination Ñ -acyl-以及Ñ -sulfonylanilines。
• A <i>para</i> -C-H Functionalization of Aniline Derivatives via In situ Generated Bulky Hypervalent Iodinium Reagents

  DOI：10.1002/ejoc.201801058

  日期：2018.11.25

  A general para‐selective C‐H functionalization was achieved via a steric control strategy. Para‐iodo, bromo, chloro, nitro, and trifluormethyl aniline derivatives were prepared via in situ generated, bulky hypervalent iodinium reagents in as little as 10 min. Products can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work‐up

  通过空间控制策略可实现一般的对选择性C-H功能化。对碘，溴，氯，硝基和三氟甲基苯胺衍生物可在短短10分钟内通过原位生成的大体积高价碘试剂制备。无需柱色谱或重结晶即可纯化产品，从而大大减少了浪费并简化了后处理过程。
