The synthesis of a series of substituted 9H-carbazoles by the photostimulatedSRN1 substitution reaction with diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches, the Pd-catalyzed reactions (Buchwald−Hartwig) or Cu-catalyzed reactions of 2-haloanilines with arylhalides, or 2-bromoiodobenzene with anilines, with moderate to very good isolated yields (45−89%)
