A 37 Alkyl 3-fluoroalkyl-3-oxopropionates in reactions with azolyldiazonium salts [Electronic resource] / E. V. Shchegol'kov, E. V. Sadchikova, Ya. V. Burgart, V. I. Saloutin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2008. - Vol. 57, № 3. - P612-618 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Alkyl 3-fluoroalkyl-3-oxopropionates react with antipyrinyldiazonium chloride to form 2-antipyrinylhydrazono-3-fluoroalkyl-3-oxopropionates. The use in these reactions of hetaryldiazonium salts, containing NH group in the ? position, leads to alkyl 7-fluoroalkyl-7-hydroxy-4,7- dihydroazolo[5,1-c]triazine-6-carboxylates. 3-Amino-1H-1,2,4-triazole, 3-amino-4-ethoxycar- bonyl-1H-pyrazole, and 5-amino-4-ethoxycarbonyl-1H-imidazole were used as the heterocyclic component \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2008, 57 (3), 612.pdf |
