Abstract:
A method for producing a fluorinated epoxide comprising the step of reacting a fluorinated ethylenically unsaturated compound having the structure:(R1)(R2)C&boxH;C(R3)(R4) with a metal hypohalite oxidizing agent in the presence of a phase transfer catalyst to produce the fluorinated epoxide having the structure: wherein R1 is selected from the group consisting of H and OR, where R is C1-C10 alkyl; R2 is selected from the group consisting of H, F, C1-C10 perfluoroalkyl, and X-substituted C1-C10 alkyl, wherein X is F, Cl, Br, I, OH, or OR; R3 and R4 are each independently selected from the group consisting of C1-C10 perfluoroalkyl, C(Rf)(Rfâ€²)OH, C1-C10perfluoroalkoxy, C1-C10 carboalkoxy, and hydroxy-substituted C3-C10 carboalkoxymethyl-substituted C1-C4 perfluoroalkyl.
