Six chlorofluoropropionyl fluorides were synthesized by converting a -CCl3 group in perhalogenated chlorofluoropropanes to a -COF group in two reaction steps.The ionic telomerization of the acyl fluorides with hexafluoropropene oxide, catalyzed by fluoride ion, afforded mainly a mixture of 1:1 to 1:3 telomers.In some cases, substitution of chlorine for fluorine in the acyl moiety and hexafluoropropene oxide oligomerization occured as side reactions.The effect of the number of chlorines in the starting acyl fluoride on the telomer distribution and by product formation is discussed.The reactivity order of the acyl fluorides Y-COF in the telomerization reaction was: CF3-CClF (2a), CClF2-CF2 (2b) > CF3-CCl2 (3a),CClF2-CClF (3b) > CClF2-CCl2 (4a), CCl2F-CClF (4b).Possible reaction pathways are discussed.
