    摘要: Disclosed in one embodiment is a process for the synthesis of 1,3,3,3-tetrafluoropropene that comprises (a) reacting a compound of formula (I) X1X2 with a compound of formula (II) CF3CH=CH2 to produce a reaction product comprising a compound of formula (III) CF3CHX1CH2X2, wherein X1 and X2 are each independently selected from the group consisting of hydrogen, chlorine, bromine and iodine, provided that X1 and X2 are not both hydrogen; (b) when X2 in formula (III) is not fluorine, fluorinating the compound of formula (III) to produce a reaction product comprising a compound of formula (III) wherein X1 is as described above and X2 is fluorine; and (c) exposing said compound of formula (III) to reaction conditions effective to convert said compound to 1,3,3,3,-tetrafluoropropene. In another embodiment, the process comprises (a) reacting chlorine with a compound of formula (I) CH3CH=CH2 to produce a reaction product comprising a compound of formula (II) CCI3CHC1CH2C1; (b) fluorinating the compound of formula (II) to produce a reaction product comprising a compound of formula (III) CF3CHC1CH2F; and (c) exposing said compound of said formula (III) to reaction conditions effective to convert said compound to 1,3,3,3-tetrafluoropropene.
