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 X1 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).
