S 81 Stable sigma-adducts of 4,6-dinitrotetrazolo[1,5-a]pyridine with alkoxide anions [Electronic resource] / I. E. Filatov, G. L. Rusinov, O. N. Chupakhin, X. Solans, M. Font-Bardia, M. Font-Altaba // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 1994. - Vol. 43, № 7. - P1214-1219 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The reaction of 2-chloro-3,5-dinitropyridine with two equivalents of KN3 in the presence of ROH results in stable Meisenheimer-type -adducts of 4,6-dinitrotetra-zolo[1,5-a]pyridine with RO– anions (R = H, Alk, Ph). The mechanism of -complex formation was suggested. The structure of the -adduct with R = Me was established by IR and NMR spectroscopy and by X-ray diffraction analysis. \\\\Expert2\\nbo\\Russian Chemical Bulletin\\1994, 43 (7), 1214.pdf |
