Abstract
Described herein is a process for the manufacture of hydrofluoroalkanols of the structure RfCFClCHROH. Also described herein are methods of manufacturing hydrofluoroalkenes of the structure RfCF═CHR from halofluorocarbons of the structure RfCFX2. In particular, 2,3,3,3,-tetrafluoro-1-propene may be manufactured with this process. Also described are compounds of the formula RfCFClCHROC(═O)R′.
