catalyzed N,N-diarylation reaction of amides with various di(o-bromoaryl)methanes to produce diverse 9,10-dihydroacridine derivatives. The resulting 9,10-dihydroacridine derivatives were oxidized selectively under mild conditions to afford acridine, acridinone, and acridinium derivatives. The copper-catalyzed N,N-diarylation reaction coupled with oxidative aromatization reaction enabled the facile construction
我们在本文中报道了CuI / DMEDA催化酰胺与各种二(邻-溴芳基)甲烷的N,N-二芳基化反应,以产生各种9,10-二氢ac啶衍生物。在温和条件下选择性氧化所得的9,10-二氢ac啶衍生物,得到afford啶,a啶酮和a啶鎓衍生物。铜催化的N,N-二芳基化反应与氧化芳构化反应相结合,使得能够容易地构建具有不同邻位熔融模式的氮原子嵌入的四碳烯和并五碳烯。还证明了发光特性,特别是融合模式对获得的N-多态荧光发射的影响。
