• Room Temperature Coupling of Aryldiazoacetates with Boronic Acids Enhanced by Blue Light Irradiation
  作者：Amanda F. Silva、Marco A. S. Afonso、Rodrigo A. Cormanich、Igor D. Jurberg

  DOI：10.1002/chem.201905812

  日期：2020.5.4

  visible-light-promoted photochemical protocol is reported for the coupling of aryldiazoacetates with boronic acids. This photochemical reaction shows great enhancement compared to the same protocol performed in the absence of light. Except for a few cases, the room temperature coupling in the dark (thermal process) generally does not work. When it does, it is likely to also involve free carbenes as key intermediates

  据报道可见光促进的光化学方案用于芳基重氮乙酸酯与硼酸的偶联。与没有光照的相同方案相比，这种光化学反应显示出极大的增强。除少数情况外，在黑暗（热过程）中的室温耦合通常不起作用。如果这样做的话，很可能还涉及到游离卡宾作为关键中间体。可替代地，光化学反应显示出广泛的范围，可以在空气中进行并且耐受各种各样的官能团。反应进化监测，DFT计算和控制实验已用于评估这种复杂机制的主要方面。具有生物活性的分子阿迪芬，苯那西嗪和阿普生已经被制备为合成应用的实例。

• Zirconium catalyzed amide formation without water scavenging
  作者：Helena Lundberg、Fredrik Tinnis、Hans Adolfsson

  DOI：10.1002/aoc.5062

  日期：2019.9

  A scalable homogeneous metal‐catalyzed protocol for direct amidation of carboxylic acids is presented. The use of 2–10 mol% of the commercially available Zr(Cp)2(OTf)2·THF results in high yields of amides at moderate temperature, using an operationally convenient reaction protocol that circumvents the use of water scavenging techniques.
