We report herein an efficient Pd‐catalyzed direct CH bond functionalization of heteroarenes via an isocyanide insertion strategy for the synthesis of di‐(hetero)aryl ketones and di‐(hetero)aryl alkylamines. The methodology involves a three component reaction between an azole, a haloarene and an isocyanide resulting in the formation of an imine, which in turn is either hydrolyzed or reduced to get
我们在此报告了通过异氰酸酯插入策略合成二(杂)芳基酮和二(杂)芳基烷基胺的有效的Pd催化杂芳烃的直接CH键官能化。该方法涉及在吡咯,卤代芳烃和异氰酸酯之间的三组分反应,导致形成亚胺,然后将其水解或还原以得到所需产物。
