ABSTRACT:
A process for coupling two low molecular weight telomers of chlorotrifluoroethylene comprises reacting the telomers with hydrogen in the presence of an effective amount of a catalyst to form a coupled olefin. The catalyst comprises palladium, platinum, rhodium, ruthenium, Raney nickel, Raney cobalt, and mixtures thereof, either supported or unsupported. The olefin can be fluorinated using a suitable fluorinating agent, such as chlorine trifluoride, to form a saturated telomer.
