CATALYSED SYNTHESIS OF FLUORINATED ALKENES AND FLUORINATED ALKENE COMPOSITIONS
A method of producing a fluoroolefin includes contacting a compound of formula (1), R f CX 1 ═CHCF 3 , with a fluorinated ethylene compound of formula (2), CX 2 X 3 ═CX 4 X 5 in the presence of a catalyst. In the compound of formula (1), R f is a linear or branched C 1 -C 10 perfluorinated alkyl group and X 1 is H, Br, Cl, or F. In the compound of formula (2), X 2 , X 3 , X 4 , and X 5 are each independently H, Br, Cl, or F and at least three of X 2 , X 3 , X 4 , and X 5 are 10 F. The resulting composition comprises a compound of formula (3), R f (CF 2 ) n CX 6 ═CH(CF 2 ) m CX 7 X 8 CFX 9 X 10 . In the compound of formula (3), X 6 , X 7 , X 8 , X 9 , 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).
