ABSTRACT:
This invention concerns a process for the production of polyfluoroolefins by the catalytic addition of polyfluoroallylic fluorides to fluoroethylenes. 1:1 and 1:2 Adducts such as F-pentene-2 and F-heptene-3 can be formed selectively and reduced further to dihydro- or trihydropolyfluoroalkanes, which are useful as HFC cleaning agents.
