| 摘 要： | Carbazole and its derivatives have attracted the attention due to its photophysical and photochemical properties as well as biological activities1. So far considerable amounts of carbazole derivatives were prepared to probe the nature of electronic states. Among these carbazole derivatives, carbazole-9-carboxylic acids were important intermediates because the carboxylic group is an active function group for further transformation into other functions. The molecular packing modes of carboxylic …

| Abstract: | The rapid synthesis of 3-bromocarbazole-N-acetic acid was performed using microwave irradiation. Under the optimal conditions the yield was 85.6 %. The crystal structure showed that the carboxylic groups form bifurcated hydrogen bonds and the hydroxyl oxygen atoms serve as proton donors and also acceptor. Each carboxylic group was involved in four hydrogen bonds. The packing of crystal was dominated by links of these hydrogen bonds. |
