We describe a practical method for the preparation of the 6H‐dibenzo‐[b,h]carbazole scaffold by utilizing a Pd‐catalyzed intramolecular amination of 3‐amino‐3′‐bromo‐2,2′‐binaphthyl. This compound showed a greater λmax and λem red‐shift and a smaller HOMO‐LUMO gap than the 9H‐carbazole. Furthermore, derivatization on the nitrogen atom provided a series of compounds.

6H-二苯并[b,h]咔唑及其衍生物的高效合成,结构表征和光学性质

我们描述了一种利用Pd催化的3-氨基-3'-溴-2,2'-联萘的分子内胺化制备6H-二苯并[b,h]咔唑支架的实用方法。与9H-咔唑相比,该化合物的λmax和λem红移更大,HOMO-LUMO间隙更小。此外,在氮原子上的衍生化提供了一系列化合物。
