Abstract: | Trifluoroacetylation of 3-halo-9-methylcarbazoles at 110C proceeds at 6-position. In the case of 3-bromo- and 3-iodo-derivatives, the reaction is complicated by competing processes of dehalogenation, followed by the halogenation of the substrate, leading to 3,6-dihalo derivatives.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1492–1495, November, 1987. |
