- ARYLPOLYFLUOROLEFIN PEROXIDES. I. SYNTHESIS OF α,β,β-TRIFLUOROSTYRENE, β-CHLORO-α,β-DIFLUOROSTYRENE, AND (PERFLUOROPROPENYL)BENZENE EPOXIDES
-
By the oxidation of α,β,β-trifluorostyrene, β-chloro-α,β-difluorostyrene, and (perfluoropropenyl)benzene with oxygen in presence of chlorine and UV radiation 1,2-epoxy-1,2,2-trifluoro-1-phenylethane, 2-chloro-1,2-epoxy-1,2-difluoro-1-phenylethane, and 1,2-epoxy-1,2,3,3,3-pentafluoro-1-phenylpropane were prepared. α,β,β-Trifluorostyrene and β-chloro-α,β-difluorostyrene epoxides under the action of triethylamine are rearranged into difluorophenylacetyl and chlorofluorophenylacetyl fluorides, by the hydrolysis of which the corresponding acids are obtained. β-Chloro-α,β-difluorostyrene epoxide reacts with fluoride ions with the formation of a mixture of chlorofluorophenylacetic acid and 2,2,2-trifluoro- and 2-chloro-2,2-difluoro-acetophenones.
