oxygen atmosphere with gentle heating. Until now, the synthesis of N-arylated cyclic imides having six-membered rings was restricted largely to strongly heating anilines in the presence of anhydrides. This reaction is applicable to the synthesis of new organic materials based on arylene imide and bis(imide) dyes, such as perylene-3,4:9,10-bis(dicarboximide)s.
显示在六元环内的环状酰亚胺在胺碱和氧气气氛下,在温和加热下,使用由乙酸铜(II)介导的各种芳基硼酸酯进行有效的N-芳基化。迄今为止,具有六元环的N-芳基化环状酰亚胺的合成主要限于在酸酐存在下强力加热苯胺。该反应适用于合成基于亚芳基酰亚胺和双(酰亚胺)染料的新有机材料,例如per 3,4:9,10-双(二甲酰亚胺)。
