A process for preparing 1,3-dioxolanes of formula:n n wherein; n X₁, X₂, X₃ and X₄, like or different from one another, represent F, Cl, Br, I, CF₂OSO₂F, SO₂F, C(O)F, H, perhaloalkyl or oxyperhaloalkyl radicals containing from 1 to 5 carhon atoms, n X₅ and X₆, like or different from each other, represent F or CF₃. Said process is characterized in that a bis(fluoroxy)perfluoroalkane is reacted, at a temperature ranging from -140°C to +60°C, with a halogenated olefin. n New 1,3-dioxolanes of formula (I) belonging to the class defined hereinbefore. |
