R 30 Reaction of polyfluoro-3-chloro(bromo)-1-butenes with sodium hypohalites and properties of epoxides derived therefrom [Electronic resource] / A. Ya. Zapevalov, V. I. Filyakova, M. I. Kodess, V. I. Saloutin // Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii). - 2003. - Vol. 39, № 7. - P919-923. - Bibliogr. : p. 923 (13 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): DERIVATIVE -- CARBON -- CESIUM -- EPOXIDE -- HYPOHALITES -- SODIUM HYPOHALITES Аннотация: Epoxidation of 3-chloro(bromo)heptafluoro-1-butenes and 3,4-dichlorohexafluoro-1-butene with aqueous solutions of sodium hypohalites is accompanied by cleavage of the carbon skeleton at the double bond and formation of polyfluorocarboxylic acid sodium salts as by-products. 3-Chloro(bromo)-1,2- epoxyheptafluoro- and 3,4-dichloro-1,2-epoxyhexafluorobutanes were synthesized and subjected to isomerization into carbonyl compounds by the action of cesium fluoride or antimony pentafluoride. \\\\Expert2\\nbo\\Russian Journal of Organic Chemistry\\2003, 39 (7), 919.pdf |
