Compounds containing the iminodibenzyl and iminostilbene ring systems are prevalent in medicinal targets and functional materials. Herein, we report palladium‐catalyzed conditions for the N‐arylation of these ring systems. This protocol could be applied to a variety of (hetero)aryl chloride and bromide substrates, including ones, which are sterically hindered or those containing a variety of functional
含有亚氨基二苄基和亚氨基二苯乙烯环系统的化合物在药物靶标和功能材料中很普遍。在本文中,我们报告了这些环系统N芳构化的钯催化条件。该方案可应用于多种(杂)芳基氯和溴化物底物,包括空间受阻的底物或含有多种官能团的底物。通过使用低钯催化剂负载量(0.1至1 mol%),第四代Palladacycle预催化剂的使用使优良的收率得到了很好的体现。
