Despite significant advances in the catalytic direct arylation of heteroarenes, the application of this reaction to pyridines has been met with limited success. An oxidative nucleophilic arylation strategy has been developed to overcome this problem. Pyridine, pyrazine, quinolone, and related electron‐deficient N‐heteroarenes can be arylated at the most electrophilic site using the developed nickel‐catalyzed
尽管在杂芳烃的催化直接芳基化方面取得了重大进展,但该反应在吡啶上的应用却取得了有限的成功。为了克服该问题,已经开发了一种氧化亲核芳基化策略。吡啶,吡嗪,喹诺酮和相关的电子不足的N-杂芳烃可以通过发达的镍催化反应在最亲电的位置被芳基化。该协议可作为催化直接芳基化反应的补充方法。
