Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): 1,4-DIAZINIUM SALTS -- INDOLES -- AZINIUM CATIONS Аннотация: N(1)-Alkyl-3-morpholino-1,2,4-triazinium salts and N(1)-alkyl-3-pyrrolidino-1,2,4-triazinium salts were synthesized. The structures of these salts were established by 13C NMR spectroscopy. 1,2,4-Triazinium cations add indoles at C(5) and C(6) thereby displaying properties characteristic for 1,4-diazinium salts. \\\\expert2\\nbo\\Chemistry of Heterocyclic Compounds\\1986, v.22, N 11, p. 1242.pdf |
