Abstract: A method of producing a fluoroolefin includes contacting a compound of formula (1), RfCX1?CHCF3, with a fluorinated ethylene compound of formula (2), CX2X3?CX4X5 in the presence of a catalyst. In the compound of formula (1), Rf is a linear or branched C1-C10 perfluorinated alkyl group and Xi is H, Br, Cl, or F. In the compound of formula (2), X2, X3, X4, and X5 are each independently H, Br, Cl, or F and at least three of X2, X3, X4, and X5 are F. The resulting composition comprises a compound of formula (3), Rf(CF2)nCX6?CH(CF2)mCX7X8CFX9X10. In the compound of formula (3), X6, X7, X8, X9, and X10 are each independently H, Br, Cl, or F, and the total number of each of H, Br, Cl, and F corresponds to the total number of each of H, Br, Cl, and F provided by the compounds of formulae (1) and (2).

Abstract: A method of producing a fluoroolefin includes contacting a compound of formula (1), RfCH?CHF, with a fluorinated ethylene compound of formula (2), CX1X2?CX3X4 in the presence of a Lewis acid catalyst. In the compound of formula (1), Rf is a C1-C10 perfluorinated alkyl group. In the compound of formula (2), X1, X2, X3, and X4 are each independently H, Cl, or F and at least one of X1, X2, X3, and X4 is F. The resulting composition comprises a compound of formula (3), RfCF3(CX5X6CX7X8)nCH?CHCX9X10CX11X12F. In the compound of formula (3), X5, X6, X7, X8, X9, X10, X11, and X12 are each independently H, Cl, or F, n is an integer of 0 or 1, and the total number of each of H, Cl, and F corresponds to the total number of each of H, Cl, and F provided by the fluorinated ethylene compound of formula (2).
