• Copper-Mediated CH/CH Biaryl Coupling of Benzoic Acid Derivatives and 1,3-Azoles
  作者：Mayuko Nishino、Koji Hirano、Tetsuya Satoh、Masahiro Miura

  DOI：10.1002/anie.201300587

  日期：2013.4.15

  intermolecular direct biaryl coupling of benzoic acid derivatives and 1,3‐azoles has been developed. The key to success is the installation of an amide‐based bidentate coordinating group, which is easily removed and transformed into the parent ester groups after the coupling reaction. Kinetic studies indicate that the rate‐limiting step is the aromatic CH bond cleavage of benzoic acid derivatives.
