Nucleophilic aromatic substitution (SNAr) reaction in classic textbook is a stepwise mechanism, and few examples of concerted reactions have been reported. Herein, we developed a concerted SNAr reaction of 5-bromo-1,2,3-triazines with phenols in which the nonclassic mechanism of this reaction could be revealed by calculation. Furthermore, the resulting 5-aryloxy-1,2,3-triazines could be used as convenient
经典教科书中的亲核芳族取代(S N Ar)反应是逐步机制,很少有协同反应的例子报道。在此,我们开发了 5-bromo-1,2,3-triazines 与酚类的协同 S N Ar 反应,其中该反应的非经典机理可以通过计算揭示。此外,所得的 5-芳氧基-1,2,3-三嗪可用作方便的前体,以一锅法获得生物学上重要的 3-芳氧基-吡啶。
