C 57 Chupakhin, O. N. Reactions of N-alkylazinium cations. Reaction of acridinium salts with enamines [Electronic resource] / O. N. Chupakhin, V. N. Charushin, E. O.

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 |
