“…Whilst the chemistry of perfluorinated alkenes is well established, alkenes with both alkyl and trifluoromethyl, or pentafluoroethyl substituents, are less common and only a few examples concerning their reactivity with hydrogen have been published [19,20]. In these reports, the reactions were performed under high pressure (100 bar) with palladium on charcoal as catalyst and during a long time, until the conversion of the alkenes was complete.…”
