Nickel‐catalyzed benzylation reactions of C−H bonds in aromatic amides with benzyltrimethylammonium halides are developed by using a 5‐chloro‐8‐aminoquinoline derivative as a bidentate directing group. Benzylation occurs selectively at the ortho‐C−H bonds in aromatic amides, and no methylation was detected. The presence of a 5‐chloro‐8‐aminoquinoline moiety is essential for the success of this reaction
通过使用5-氯-8-氨基喹啉衍生物作为双齿导引基团,开发了芳香族酰胺中的CH键与镍三卤化苄基进行镍催化的苄基化反应。苯甲酰化选择性地发生在芳族酰胺的邻-C-H键上,未检测到甲基化。5-氯-8-氨基喹啉部分的存在对于该反应的成功至关重要,在该反应中可以耐受多种官能团。
