| Abstract: | Condensation of 9-phenanthrylhydrazine hydrochloride with pyruvic acid and its ethyl ester gave the corresponding hydrazones, Fischer cyclization of which yielded 2-carboxy- and 2-carbethoxy-4,5,6,7-dibenzindoles. 4,5,6,7-Dibenzindole was obtained by decarboxylation of 2-carboxy-4,5,6,7-dibenzindole, and its IR, UR, PMR, mass, and luminescence spectra were studied.See [1] for communication XV.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1061–1065, August, 1978. |
