| Abstract: | 2,6-Diphenyl- and 2,6-di-tert-butylpyrylium salts react with excess hydrazine to give 1,2-diazeplne derivatives. Under the same conditions, 4-(1-methyl-3-indolyl)flavylium perchlorate forms 3-phenyl-5-(1-methyl-3-lndolyl)pyrazole.Translated from Khimiya Geterotsiklichesikikh Soedinenii, No. 1, pp. 45–48, January, 1973. |
