• Selectfluor-mediated oxidative methylenation of amide with <i>N</i>,<i>N</i>-dimethylpropanamide for <i>N</i>,<i>N</i>′-methylenebisamide synthesis
  作者：Yue Cao、Dongheng Zhou、Yongmin Ma

  DOI：10.1139/cjc-2018-0181

  日期：2019.1

  A simple and efficient approach for the synthesis of N,N′-methylenebisamides through a Selectfluor-mediated oxidative reaction of aromatic amides and N,N-dimethylpropanamide (DMP) is described. Remarkable results clearly reveal that DMP plays a dual role in this reaction, as both a one-carbon source and an environment-friendly solvent. Moreover, the process provides new strategies for the synthesis of bisamides with advantages of operationally simple, insensitive to atmospheric conditions, and good to high yields.

  通过Selectfluor介导的芳香酰胺和N,N-二甲基丙酰胺（DMP）的氧化反应合成N,N′-亚甲基双酰胺的简单高效方法被描述。显著的结果清楚地表明DMP在这个反应中发挥了双重作用，既是一个一碳源，又是一种环境友好的溶剂。此外，该过程提供了合成双酰胺的新策略，具有操作简单、不受大气条件影响和产率良好至高的优点。
