| Abstract: | An analysis of the PMR spectra (using double resonance) of the isomeric 3-, 6-, 7-, and 8-methyl and 7-ethyl-5-azacinnolines, and also of 7-methyl-8-azacinno-line has shown the presence in these structures of a considerable localization of the C5-C6 and C7-C8 bonds, which has been confirmed by the results of a quantum-chemical calculation by the PPP method.Deceased.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 541–543, April, 1980. |
