Abstract
The salt [CF3CCXe] [BF4] was prepared as neat compound by the reaction of the hitherto unknown alkynyldifluoroborane CF3CCBF2 with XeF2 in 1,1,1,3,3-pentafluoropropane (PFP) at −45 °C in 59% yield. [CF3CCXe] [BF4] was unambiguously characterised by multinuclear NMR spectroscopy in anhydrous HF (aHF) solution.Keywords
