Abstract
Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CFCF═CH(1234yf). In certain preferred embodiments the processes comprise first exposing a compound of Formula (IA)C(X)═CClC(X)  (IA)where each X is independently F, Cl or H, preferably CCl═CClCHCl, 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):CFCClX'C(X′)  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)CFCF═CHZ  (II)where Z is H, F, Cl, I or Br.
