An efficient palladium‐catalyzed CH functionalization of aldehydes with various N‐substituted N‐heteroarene‐2‐carboxamides has been developed for the synthesis of secondary imides. The reaction tolerates various functionalities, such as methoxy, fluoro, chloro, and bromo groups. A tentative radical mechanism for a PdII/PdIV catalytic cycle is proposed.
已经开发出了一种高效的钯催化的醛用各种N-取代的N-杂芳烃-2-羧酰胺进行的CH官能化反应,以合成仲酰亚胺。该反应容许各种官能团,例如甲氧基,氟,氯和溴基团。提出了Pd II / Pd IV催化循环的暂定自由基机理。
