T 82 Transformations of C-adducts of 1,4-diazinium salts with dicarbonyl compounds into polycyclic systems [Electronic resource] / E. V. Verbitskiy, P. A. Slepukhin, G. L. Rusinov, V. N. Charushin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2008. - Vol. 57, № 3. - P652-656 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: C-Adducts of 5-(het)aryl-2,3-dicyano-1-pyrazinium salts containing a residue of a 1,3-dicarbonyl compound at position 6 can be involved in the cyclization with hydrazine hydrate giving rise to pyrazino[2,3-c]pyridazines along with the expected pyrazole derivatives. The reactions of the same ?H-adducts with hydroxylamine unexpectedly afforded triazacyclopenta[a]indene derivatives. The crystallographic data on the three-dimensional structures of new polycyclic compounds were obtained \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2008, 57 (3), 652.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): PYRIDAZINES -- HETEROCYCLIC SUBSTITUENTS -- CARBORANE MOIETY Аннотация: The structures and characteristic features of the molecular packing patterns of complexes of pyridazines containing heterocyclic substituents and the carborane moiety with 2,3,5,6-tetrachlorohydroquinone (TCHQ) were investigated. It was shown that TCHQ can form supramolecular assemblies with carborane-containing substituted pyridazines. The stoichiometry and three-dimensional structures of these assemblies depend on the substituents in the pyridazine ring and are formed via O-H⋯N hydrogen bonding between TCHQ and heterocyclic molecules \\\\expert2\\NBO\\Crystallography Reports (Кристаллография)\\2014, v.59, N 2, p.202-206.pdf |
