The nitration in 1,2-dichloroethane of carbazole and N-alkylcarbazoles
, which were synthesized using a phase-transfer reaction, was studied.
The results show that 3-nitrocarbazoles and 3,6-dinitrocarbazoles are
the main reaction products. Both the reaction conditions and the natu
re of the N-alkyl group influence the formation of; and the ratio of,
the mononitrocarbazoles and dinitrocarbazoles.
