Abstract

Abstract Carbazole (1) undergoes electrophilic aromatic substitution with various chlorinating reagents. Although 3-chlorocarbazole (1b), 3, 6-dichlorocarbazole (1d) and 1, 3, 6, 8-tetrachlorocarbazole (1f) obtained by chlorination of carbazole were isolated and characterized sometime ago, 1-chlorocarbazole (1a), 1, 6-dichlorocarbazole (1c) and 1, 3, 6- trichlorocarbazole (1e) had never been isolated from the reaction mixtures.
