In a novel process for the preparation of perfluoroalkylalkenols, perfluoroalkylhalohydrins are dehydrohalogenated using specific ionic bases, namely using an alkali metal carbonate, an alkali metal hydrogen carbonate or an alkylammonium hydrogen carbonate, in the presence of aprotic and polar solvents. Using this process, high yields of the intended perfluoroalkylalkenols are achieved and only very small amounts, if any at all, of undesired byproducts, such as partially fluorinated ether alcohols and/or partially fluorinated epoxides, are formed. |
