Abstract
A process for producing a producing a product of the formula: R—CF═CHR1 wherein R is F or CF3 and R1 is F when R is F and is H when R is CF3 by reacting a reactant of the formula: CF3—R2 wherein R2 is selected from wherein R3 is H, F or Cl and R4 is H or Cl, in the presence of a suitable catalyst, with a reducing agent selected from methane, methyl chloride and mixtures thereof, in a gas phase reaction.
