The dissolution of (perfluoroorgano)difluoroboranes RFBF2 in anhydrous HF (aHF) resulted in equilibrium mixtures of the starting borane and different kinds of acid-base products: [H2F] [RFBF2(F.HF)] (R-F=C6F5, cis-C2F5CF=CF, trans-C4F9CF=CF) or [H2F] [RFBF3] (RF=C6F13). In aHF the aryl compounds C6F5BF2 and K [C6F5BF3] showed two parallel reactivities with XeF2: xenodeborylation (formation of the [C6F5Xe](+) cation) and fluorine addition to the aryl group. In aHF perfluoroalk-1-enyldifluoroboranes RFBF2 as well as potassium perfluoroalk-1-enyltrifluoroborates K [RFBF3] (R-F=cis-C2F5CF=CF, trans-C4F9CF=CF) underwent only fluorine addition across the carbon-carbon double bond under the action of XeF2. Potassium perfluorohexyl-trifluoroborate K [C6F13BF3] did not react with XeF2 in aHF.
