The straightforward synthesis of N,N-disubstituted formamides using a combination of 1,1,1,3,3,3-hexafluoroispropanol (HFIP) and H2O2 is described. The unique features of HFIP allowed the utilization of a green oxidant such as H2O2, and the products, arising from an oxidation–rearrangement sequence, were obtained in good to high yields under smooth reaction conditions.
描述了使用1,1,1,3,3,3-六氟异丙醇(HFIP)和H 2 O 2的组合直接合成N,N-二取代甲酰胺。HFIP的独特功能允许利用绿色氧化剂(例如H 2 O 2),并且在平稳的反应条件下,以高至高收率获得了由氧化重排序列产生的产物。
