  受经典胺化反应启发的吡啶和二嗪的选择性 CH 氟化

  摘要：

  氟化吡啶 将氟取代基附加到碳中心通常用于调节药物和农业化学研究中的小分子特性。然而，氟化通常需要使用腐蚀性、危险的试剂。Fier 和 Hartwig (p. 956) 提出了一种异常温和且方便的方案，用于氟化吡啶和相关含氮芳烃中与氮相邻的碳位点。该反应需要用二氟化银处理并在室温下快速进行。温和的氟化方法可以帮助生产医学研究中感兴趣的化合物。氟化杂环广泛存在于药物、农用化学品和材料中。然而，将氟结合到杂芳烃中的反应范围有限并且可能是危险的。我们提出了一种广泛适用且安全的方法，用于使用市售的氟化银 (II) 对吡啶和二嗪中的单个碳氢键进行位点选择性氟化。反应在环境温度下在 1 小时内发生，并且对氮附近的氟化具有唯一的选择性。温和的条件允许获得具有重要医学意义的化合物的氟化衍生物，以及通过随后的氟化物亲核置换制备的一系列 2-取代吡啶。机理研究表明，经典的吡啶胺化途径可适用于广泛范围的氮杂环的选择性氟化。反应在环境温度下在

• Amination of Aromatic Halides and Exploration of the Reactivity Sequence of Aromatic Halides
  作者：Chu Yang、Feng Zhang、Guo-Jun Deng、Hang Gong

  DOI：10.1021/acs.joc.8b02588

  日期：2019.1.4

  A base-promoted amination of aromatic halides has been developed using a limited amount of dimethylformamide (DMF) or amine as an amino source. Various aryl halides, including F, Cl, Br, and I, have been successfully aminated in good to excellent yields. Although the amination of aromatic halides with amines or DMF is usually considered as an aromatic nucleophilic substitution (SNAr) process, and the

  使用有限量的二甲基甲酰胺（DMF）或胺作为氨基源，已经开发出碱促进的芳香族卤化物胺化。包括F，Cl，Br和I在内的各种芳基卤化物均已成功地以良好或优异的收率胺化。尽管通常将胺或DMF芳香卤化物胺化视为芳香亲核取代（S NAr）过程，芳族卤化物的反应性为F> Cl> Br> I，发现该体系中芳族卤化物的反应性为I> Br≈F> Cl。该方案还显示了对多卤代芳烃的良好区域选择性。由于操作简单，氨基源和芳族卤化物的不受限制的可用性，无过渡金属的条件，不需要溶剂以及可扩展性，该协议对于工业应用很有价值。

  Presented herein is a general protocol for the alkylation of simple aryl fluorides with unbiased secondary Grignard reagents by means of nickel catalysis. This study revealed a general Thorpe–Ingold effect in the ligand backbone which confers a high degree of selectivity for the secondary carbon center in the C−C coupling event. This protocol is characterized by mild reaction conditions, robustness

  本文提出了通过镍催化用无偏的二次格氏试剂将简单的芳基氟化物烷基化的一般方案。这项研究揭示了配体主链上普遍的索普-英戈尔德效应，在CC偶合事件中赋予了次级碳中心高度的选择性。该协议的特点是反应条件温和，稳健且简单。富电子和缺电子的芳基氟化物都是该转化的合适候选物。同样适合的是各种杂环，允许偶联而在亲电子位点没有过度烷基化。
