DOI: 10.1080/10406638.2018.1458739
Abstract: ABSTRACT The unexpected result for the formylation of N-ethylcarbazole under the Vilsmeier–Haack conditions (POCl3/DMF) led to the synthesis of novel methylene bridged bis-pyrrolo[3,2-c]carbazoles via Hemetsberger indole synthesis was reported. A plausible mechanism for the formation… read more here.
