    摘要: 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.
