In an embodiment, a method of producing a fluoroolefin comprises
coupling 3,3-dichloro-1,1,1,2,2-
pentafluoropropane (CF3-CF2-CHCl2) in a
liquid phase in the presence of a catalyst to form a composition comprising 1,1,1,2,2,5,5,6,6,6-decafluoro-3-
hexene (CF3CF2CH=CHCF2CF3). In another embodiment, a method of producing a fluoroolefin comprises
coupling 1,1,1-trichloropentafluoropropane (CF3-CF2-CCl3) in a
vapor phase in the presence of a first catalyst to form a composition comprising 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-
hexene (CF3-CF2-CCl=CCl-CF2-CF3). The method may further include forming the CF3-CF2-CCl3 in a
vapor phase from CF3CF2CHmCl3-m and
chlorine (Cl2). The method may further include hydrodechlorinating the 3,4-dichloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-
hexene with
hydrogen (H2) in a
vapor phase in the presence of a second catalyst to form a composition comprising CF3CF2CH=CHCF2CF3 and 3-chloro-1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene (CF3CF2CCl=CHCF2CF3).
