Заглавие : Reactions of pyrazinium salts with phenols:from σH-adducts to SN Hproducts and transformations into benzo[b]furans Место публикации : Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2011. - Vol.60, №5. - С. 919-928 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): dihydropyridines--nucleophilic substitution--hydrogen Аннотация: The reaction of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium salts with phenol derivatives affords relatively stable dihydropyrazines, whereas the reactions of 6-(het)aryl-1,2,5-oxadiazolo[3,4-b]pyrazin-4-ium protic salts, depending on the phenol structure, result in products of nucleophilic substitution of hydrogen or open-chain transformation products: benzo[b]furan-substituted derivatives. The crystallographic data on the spatial structure of all types of the synthesized products were obtained Доп.точки доступа: Verbitskiy, E. V.; Kvashnin, Yu. A.; Slepukhin, P. A.; Kuchin, A.
