Abstract The reactions of epoxy derivatives of internal perfluoroolefins with o- phenylenediamine and 2-aminophenol in dioxane gave 23–67% of the corresponding 2, 3- bis (perfluoroalkyl) quinoxalines and 2, 3-bis (perfluoroalkyl)-2 H-1, 4-benzoxazin-2-ols, respectively. When N, N-dimethylacetamide was used as a solvent, the main reaction pathway was anionic isomerization of epoxides into ketones which were then converted ...
