1,3,3,3－四氟丙烯和2,3,3,3－四氟丙烯的合成方法
摘要：
在一个实施方案中公开了合成1，3，3，3－四氟丙烯的方法，包括：(a)使式(I)X1X2的化合物与式(II)CF3CH＝CH2的化合物反应以生产包括式(III)CF3CHX1CH2X2的化合物的反应产物，其中X1和X2各自独立地选自氢、氯、溴和碘，条件是X1和X2不都为氢；(b)当式(III)中的X2不是氟时，氟化式(III)的化合物以生产包括式(III)化合物的反应产物，其中X1如上所述和X2是氟；和(c)暴露所述式(III)的化合物于有效反应条件以将该化合物转化成1，3，3，3－四氟丙烯。在另一个实施方案中，该方法包括(a)使氯与式(I)CH3CH＝CH2的化合物反应以生产包括式(II)CCl3CHClCH2Cl的化合物的反应产物；(b)氟化式(II)的化合物以生产包括式(III)CF3CHClCH2F的化合物的反应产物；和(c)暴露所述式(III)的化合物于有效反应条件以将该化合物转化成1，3，3，3－四氟丙烯。
摘要（英）：

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) X<1>X<2> with a compound of formula (II) CF3CH=CH2 to produce a reaction product comprising a compound of formula (III) CF3CHX<1>CH2X<2>, wherein X<1> and X<2> are each independently selected from the group consisting of hydrogen, chlorine, bromine and iodine, provided that X<1> and X<2> are not both hydrogen; (b) when X<2> in formula (III) is not fluorine, fluorinating the compound of formula (III) to produce a reaction product comprising a compound of formula (III) wherein X<1> is as described above and X<2> 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.
