The protonation of the aromatic ring of 9-methylcarbazole under the influence of trifluoroacetic acid in 1,2-dichloroethane was established by spectrophotometry.Deuterium exchange between 9-methylcarbazole and deuterotrifluorotrifluoroacetic acid was evaluated quantitatively by means of mass spectrometry and the PMR spectra.Highly deuterated carbazole and 9-methylcarbazole were obtained for the first time.
