Kim, V. N. Charushin // Journal of Structural Chemistry. - 2008. - Vol. 49, № 6. - P1144-1148 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The products of the reaction of 2-alkenylthiopyridines with mercury iodide have been studied by single crystal X-ray diffraction. It has been demonstrated that the products are organomercury derivatives of salts of 2,3-dihydrothiazolo[3,2-a]pyridinium \\\\Expert2\\nbo\\Journal of Structural Chemistry\\2008, V. 49, N 6, p.1144.pdf |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ACRIDINIUM SALTS -- ENAMINES -- N-ALKYLAZINIUM CATIONS Аннотация: The reaction pyridinium N-methylazinium salts and their benzo analogs - quinolinium, isoquinolinium, and acridinium ions - with enamines was investigated. Acridanyl-substituted enamines, their iminium salts, and the corresponding ketones were obtained by reaction of the N-methylacridinium salts with the enamines in dimethyl sulfoxide at room temperature. The quinolinium and isoquinolinium salts have lower activities; the N-methylpyridinium cation does not react at all under the indicated conditions. \\\\expert2\\nbo\\Chemistry of Heterocyclic Compounds\\1979, v.15, N 5, p.541.pdf |
