The present invention relates to a kind of method for preparing carbazole compound, and described carbazole compound has the structure shown in general formula (I); Said method comprises following specific steps: add raw material A, rhodium catalyst, The silver catalyst, alkali and raw material B are added into an organic solvent, mixed evenly, and fully reacted at -10°C to 100°C to obtain the product. The method provided by the invention is catalyzed by transition metal rhodium, starts from multi-substituted biphenylboronic acid and multi-substituted azide, and obtains carbazole compounds in a mild, efficient and easy way through successive reactions. This method has very wide substrate adaptability, and many carbazole compounds with different substituents and aromatic heterocycles can be synthesized by this method. |
