  Trifluoromethyl-substituted biphenylcarboxylic acids are prepared by converting methyl-substituted biphenylcarbonitriles into the corresponding trichloromethyl-substituted biphenylcarbonitriles, converting the trichloromethyl group thereof to a trifluoromethyl group and thus obtaining trifluoromethyl-substituted biphenylcarbonitriles, and preparing the corresponding carboxylic acids therefrom by hydrolysis. A number of intermediates arising during this are novel compounds.

  A copper-catalyzed synthesis of phenanthridine derivatives was developed starting from biaryl-2-carbonitriles and Grignard reagents. The present transformation is carried out by a sequence of nucleophilic addition of Grignard reagents to biaryl-2-carbonitriles to form N-H imines and their Cu-catalyzed C−N bond formation on the aromatic C−H bond, where molecular oxygen is a prerequisite to achieve the

  magnesium reagent with ZnCl2. This method can also be applied to the preparation of functionalized benzylic zinc reagents from benzylic chlorides. In the case of di‐ or tribromoaryl derivatives, directing groups such as ‐OPiv, ‐OTs, ‐N2NR2, or ‐OAc orient the zinc insertion (Zn/LiCl) to the ortho‐position, while the reaction with Mg/LiCl or Mg/LiCl/ZnCl2 leads to regioselective insertion into the para‐carbon–bromine

  LiCl的存在极大地促进了镁向各种芳族和杂环溴化物中的插入。几个功能组，如-OBoc，-OTs，-Cl，-F，-CF 3，-OMe，-NMe 2和-N 2 NR 2，具有很好的耐受性。氰基的存在在某些情况下导致有机卤化物竞争性还原为相应的ArH化合物。通过ZnCl 2原位捕获中间镁试剂可以耐受甲基或乙基酯等敏感基团的存在。该方法也可用于由苄基氯化物制备官能化的苄基锌试剂。如果是二溴或三溴芳基衍生物，则应使用诸如-OPiv，-OTs，-N之类的指导基团2 NR 2或-OAc将锌插入（Zn / LiCl）定向到邻位，而与Mg / LiCl或Mg / LiCl / ZnCl 2的反应导致区域选择性插入对碳-溴键中。描述了所有金属化步骤的大规模实验（20–100 mmol）。

  ligand [2,2'-bipyridin]-6(1 H)-one (bipy-6-OH) has a strong accelerating effect on the Pd-catalyzed direct arylation of pyridine or arenes. The isolation of relevant intermediates and the study of their decomposition unequivocally show that the deprotonated coordinated ligand acts as a base and assists the cleavage of the C-H bond. Mechanistic work indicates that the direct arylation of pyridine with

  配体 [2,2'-联吡啶]-6(1 H)-one (bipy-6-OH) 对 Pd 催化的吡啶或芳烃直接芳基化具有很强的加速作用。相关中间体的分离及其分解研究明确表明，去质子化的配位配体充当碱基并有助于 CH 键的断裂。机理研究表明，吡啶与该配体的直接芳基化通过 Pd(0)/Pd(II) 循环发生。由于这种双配体-分子内碱作用，金属上不需要外部碱的可用配位位点，这是在涉及 CH 裂解步骤的偶联反应中使用螯合配体时遇到的困难。
