Abstract
A method of producing a fluoroolefin includes contacting a compound of formula (1), RCX═CHCF, with a fluorinated ethylene compound of formula (2), CXX═CXXin the presence of a catalyst. In the compound of formula (1), Ris a linear or branched C-Cperfluorinated alkyl group and Xis H, Br, Cl, or F. In the compound of formula (2), X, X, X, and Xare each independently H, Br, Cl, or F and at least three of X, X, X, and Xare F. The resulting composition comprises a compound of formula (3), R(CF)CX═CH(CF)CXXCFXX. In the compound of formula (3), X, X, X, X, and Xare 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).
