2-Methyl-1-tetralone ¦Á-naphthylhydrazone was cyclized by heating with HCl-saturated AcOH to give 6a-methyl-5,6-dihydrodibenzo[a,i]carbazole (I). Similarly were prepared 13a-methyl-5,6-dihydrodibenzo[a,g]carbazole (II) and 6a-methyl-5,6-dihydrobenzo[a]carbazole (III). The dehydrogenation of I-III over Pd/C gave 13H-dibenzo-[a,i]carba zole, 7H-dibenzo[a,g]carbazole and 11H-benzo[a]-carbazole, resp.
