• Mild Palladium-Catalyzed Cyanation of (Hetero)aryl Halides and Triflates in Aqueous Media
  作者：Daniel T. Cohen、Stephen L. Buchwald

  DOI：10.1021/ol5032359

  日期：2015.1.16

  A mild, efficient, and low-temperature palladium-catalyzed cyanation of (hetero)aryl halides and triflates is reported. Previous palladium-catalyzed cyanations of (hetero)aryl halides have required higher temperatures to achieve good catalytic activity. This current reaction allows the cyanation of a general scope of (hetero)aryl halides and triflates at 2–5 mol % catalyst loadings with temperatures

  据报道，轻度，有效和低温钯催化的（杂）芳基卤化物和三氟甲磺酸酯的氰化反应。先前钯催化的（杂）芳基卤化物的氰化需要更高的温度以实现良好的催化活性。该当前反应可以使一般范围的（杂）芳基卤化物和三氟甲磺酸酯在催化剂负载量为2％至5％的条件下从rt到40°C进行氰化。这种温和的方法适用于逆转录酶抑制剂lersivirine的合成。

• Palladium-catalyzed C-H formylation of electron-rich heteroarenes through radical dichloromethylation
  作者：Yan Bao、Jian-Yong Wang、Ya-Xuan Zhang、Yan Li、Xi-Sheng Wang

  DOI：10.1016/j.tetlet.2018.07.013

  日期：2018.8

  A novel palladium-catalyzed C-H formylation of electron-rich N-, O-, and S-containing heteroarenes has been developed. The key to success is that the commercially available BrCHCl2 was used as a stoichiometric carbonyl source. Mechanistic investigations indicated that different from the known Reimer-Tiemann reaction, this net C-H formylation proceeded through an electrophilc radical-type path.

  已经开发了新型的钯催化的富电子的N，O和S杂芳烃的CH甲酰化反应。成功的关键是将市售的BrCHCl 2用作化学计量的羰基来源。机理研究表明，与已知的Reimer-Tiemann反应不同，这种净的CH甲酰化反应是通过亲电子自由基类型的路径进行的。
