ABSTRACT:
The invention relates to a cost effective and convenient process for the manufacture of fluorinated olefins of the formula RCF.sub.2 CH=CH.sub.2 where R is C.sub.x Cl.sub.y F.sub.z and y+z=2.times.+1. The invention is also directed to a lo practical process for converting these olefins to hydrofluorocarbons via the catalyzed fluorination with hydrogen fluoride. Hydrofluorocarbons produced via this process have application as solvents among other uses.
