Rh-catalyzed direct cross-coupling of various (hetero)arenes with quinones is developed. This protocol is effective for a broad range of substrates and a wide range of directing groups.

3-b]carbazole derivatives were prepared by oxidative coupling of anilines with naphthoquinone followed by palladium catalyzed oxidative CH functionalization and a one pot reductive methylation reaction. The benzocarbazole fluorophores were photophysically characterized and the effects of the substituents investigated. (TD)-DFT calculations faithfully reproduced experimental photophysical properties of the
通过苯胺与萘醌的氧化偶合,然后钯催化的氧化C H官能化和一锅还原甲基化反应,制备了新颖的高蓝色荧光N-甲基-6,11-二甲氧基苯并[2,3- b ]咔唑衍生物。对苯并咔唑荧光团进行了光物理表征,并研究了取代基的作用。(TD)-DFT计算忠实地再现了苯并咔唑的实验光物理性质,并揭示了取代基如何影响这些化合物的光物理性质。
