S 69 S-N(H)-reactions of 1,2,4-triazine derivatives with acetophenones [Text] / G. L. Rusinov, N. A. Itsikson, D. G. Beresnev, O. V. Koryakova, O. N. Chupakhin // Heterocyclic Communications. - 2002. - Vol. 8, № 1. - P75-78 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: SNH-products were obtained by the reaction of azoloannelated 1,2,4-triazines and 3-substituted 1,2,4-triazin-5(2H)-ones with acetophenones. The reasons of extraordinary readily aromatization of ?H-adducts have been discussed. |
