Arylation of pyridines/quinolines to nitrogen-adjacent position was achieved by SNAr type reaction between pyridine/quinoline N-oxides and indoles with the help of Tf2O for the generation of highly electrophilic intermediate. The reaction proceeded in a short reaction time, open-air condition and without the use of any transition metals, affording various coupling products.
通过吡啶/喹啉 N-氧化物与吲哚之间的 S N Ar 型反应,在 Tf 2 O 的帮助下,将吡啶/喹啉向氮相邻位置芳基化,生成高亲电子中间体。该反应在短反应时间、露天条件下进行,不使用任何过渡金属,得到各种偶联产物。
