Abstract
Abstract Hexafluoro-1,3-butadiene was converted into 1,4-dibromo-hexafluoro-2-butene, 1-chloro-4-iodo-hexafluoro-2-butene and octafluoro-2-butene. Controlled oxidation of these olefins afforded 1,2-diketones in moderate yields. Condensation of the diketones with o-phenylenediamine gave the 2,3-bis(polyfluoro-alkyl)quinoxalines. Chemical reactivity of the 2,3-bis(polyfluoroalkyl)-quinoxalines in photochemically-induced reactions with poly-fluoroolefins, in organometallic reactions and in reactions with some nucleophiles, was studied.
