TRIFLUOROACETYLATION OF 9-METHYLCARBAZOLE. 2. PECULIARITIES OF THE REACTION DUE TO THE PRESENCE OF TRIFLUOROACETIC ACID
A satisfactory model of the intermediate in the formation of polyaryltrifluoromethylmethanes in the trifluoroacetylation of 9- methylcarbazole is 1,1,1-trifluoro-2,2-bis(9-methyl-3-carbazolyl)-2-hydroxyethane.The kinetic isotope effect of the reaction was evaluated.It is shown that the rate of the reaction is determined by the formation of a ? complex.The trifluoromethylation of 9-methyl-carbazole at 110 deg C is accompanied by demethylation of the substrate under the influence of trifluoroacetic acid.
