• Pd-Catalyzed Intermolecular <i>ortho</i>-C−H Amidation of Anilides by <i>N</i>-Nosyloxycarbamate
  作者：Ka-Ho Ng、Albert S. C. Chan、Wing-Yiu Yu

  DOI：10.1021/ja106364r

  日期：2010.9.22

  A palladium-catalyzed ortho-C-H amidation of anilides by N-nosyloxycarbamates was developed for the synthesis of 2-aminoanilines. This reaction can be carried out under relatively mild conditions and exhibits excellent regioselectivity and functional group tolerance. The amidation reaction is probably initiated by rate-limiting C-H cyclopalladation (k(H)/k(D) = 3.7) to form an arylpalladium complex

  作者：Qun Zhao、Tatiana Besset、Thomas Poisson、Jean-Philippe Bouillon、Xavier Pannecoucke

  DOI：10.1002/ejoc.201501217

  日期：2016.1

  We report the first introduction of 2-bromo-3,3,3-trifluoropropene (BTP) by directed C–H bond functionalization. The developed method gives straightforward access to α-(trifluoromethyl)styrene derivatives without prior prefunctionalization of the substrates. This palladium-catalysed transformation was applied to a broad range of substrates, and the corresponding trifluoromethylated products were obtained

  我们报告了通过定向 C-H 键功能化首次引入 2-溴-3,3,3-三氟丙烯 (BTP)。开发的方法可以直接获得 α-（三氟甲基）苯乙烯衍生物，而无需预先对底物进行预官能化。这种钯催化的转化应用于广泛的底物，并以良好的产率获得了相应的三氟甲基化产物。这种方法代表了以前用于访问此类分子的经典方法的替代途径。
• Equivalent Loading of Directed Arenes in Pd(II)-Catalyzed Oxidative Cross-Coupling of Aryl C–H Bonds at Room Temperature
  作者：Chong Mei、Mengdi Zhao、Wenjun Lu

  DOI：10.1021/acs.joc.0c02722

  日期：2021.2.5

  cross-couplings of aryl halides (Ar1–halo) with aryl metallics (Ar2–M) in the loading ratio of 1:1 are popular in chemical synthesis. In contrast, there has been less precedence on the same biaryls produced effectively from two normal aryl C–H bonds with equivalent loading. Here, we report that, in a palladium/oxidant/acid catalytic system at room temperature, one arene (Ar1–H, 1 equiv) can highly selectively

  在化学合成中，由芳基卤化物（Ar 1 -halo）与芳族金属（Ar 2 -M）催化交联产生的不对称联芳基（Ar 1 -Ar 2）在化学合成中很普遍。相比之下，由两个正常的芳基C–H键有效地产生的相同联芳基具有相同的负载量，则优先级较低。在这里，我们在室温下，一个芳烃报告说，在钯/氧化剂/酸催化体系（AR 1为-H，1个当量）可高选择性地夫妇与其他一个（AR 2为-H，1当量），得到目标Ar 1 –Ar 2仅通过控制其苯环上的导向基团和取代基即可。几个生物活性分子的合成也证明了这种一对一交叉偶联的效用。

  effective and practical modular flow design for the meta-selective C-H arylation of anilines. The design consists of four continuous-flow modules (i.e., diaryliodonium salt synthesis, meta-selective C-H arylation, inline copper extraction, and aniline deprotection) which can be operated either individually or consecutively to provide direct access to meta-arylated anilines. With a total residence time
