%X Trace amounts of carbazole are formed by the action of W-7J Raney nickel on aniline, diphenylamine, 2,2'-diaminobiphenyl, and 2-aminobiphenyl. Aniline yields also N-cyclohexylaniline, diphenylamine, 2,2'-diaminobiphenyl, and 2-aminobiphenyl; 2,2'-diaminobiphenyl gave 2-aminobiphenyl also. Carbazole was not detectably affected by the catalyst. These results suggest that aniline is slowly converted to carbazole (a) by way of diphenylamine; (b) by way of 2,2'-diamino- biphenyl and 2-aminobiphenyl; and (c) by way of 2,2'-diaminobiphenyl. The last route appears to be the most efficient one.
