Recent work on the synthesis of 3,6‐dibenzoylcarbazole

By heating carbazole (1) with aluminum trichloride and benzoyl chloride four benzoylcarbazole derivatives were obtained: N‐benzoylcarbazole (2), 1‐benzoylcarbazole (3), 3‐benzoylcarbazole (4) and 3,6‐dibenzoylcarbazole (5). The complete characterization of benzoylcarbazole derivatives 2–5 was performed by physical and spectroscopical methods (mp, tlc Rf, glc Tr, uv, ir, 1H nmr, 13C nmr and ms).
