  (Fluoroorgano)fluoroboranes and -borates. 7 [1] The Reaction of RFBF2 and K [RFBF3] (RF = perfluorophenyl-, perfluoroalk-1-enyl- and perfluoroalkyl) with Xenon Difluoride in Anhydrous HFDedicated to Professor Dieter Naumann on the Occasion of his 60th Birthday

  摘要：

  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.
