    • Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF═CH2 (1234yf). In certain preferred embodiments the processes comprise first exposing a compound of Formula (IA) C(X)2═CClC(X)3  (IA) where each X is independently F, Cl or H, preferably CCl2═CClCH2Cl, to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce at least one chlorofluoropropane, preferably in accordance with Formula (IB): CF3CClX′C(X′)3  Formula (IB) where each X′ is independently F, Cl or H, and then exposing the compound of Formula (IB) to one or more sets of reaction conditions, but preferably a substantially single set of reaction conditions, effective to produce a compound of Formula (II) CF3CF═CHZ  (II) where Z is H, F, Cl, I or Br.
    • 公开了用于制备氟化烯烃的方法,优选适于商业化CF 3 CF = CH 2(1234yf)。 在某些优选实施方案中,该方法包括首先将式(IA)C(X)2 = CClC(X)3(IA)的化合物暴露于其中每个X独立地为F,Cl或H,优选CCl 2 = CClCH 2 Cl, 反应条件组,但优选基本上单一组的反应条件,有效产生至少一种氯氟丙烷,优选按照式(IB):CF 3 CClX'C(X')3式(IB),其中每个X'独立地为F ,然后将式(IB)化合物暴露于一组或多组反应条件,但优选基本上单一组的反应条件,有效地制备式(II)化合物,CF 3 CF = CHZ(II) 其中Z是H,F,Cl,I或Br。
