The amination of 3-nitropyridines with aromatic amides generated from various aminopyridine derivatives proceeded unexpectedly in the position PARA to the nitro group, giving the oxidativenucleophilicsubstitution of hydrogen (ONSH) derived compounds. After optimization, this reaction allowed easy access to interesting 3-nitro-substituted N, N′-dipyridinylamines.
3-硝基吡啶与由各种氨基吡啶衍生物产生的芳族酰胺的胺化在 PARA 到硝基的位置出乎意料地进行,产生了氢 (ONSH) 衍生化合物的氧化亲核取代。优化后,该反应可以轻松获得有趣的 3-硝基取代的 N,N'-联吡啶胺。
