Abstract:
The perfluorinated organoethynylxenon(II) salts, [RC≡CXe][BF4] [R = CF3, C3F7, (CF3)2CF, cis-, trans-CF3CF=CF, C6F5], were prepared by the reaction of XeF2 with the corresponding perfluoroorganoethynyldifluoroboranes, RC≡CBF2, in 1,1,1,3,3-pentafluoropropane (PFP) or CH2Cl2 at –60 to –40 °C and isolated in 30–98 % yield. Similarly, the non-fluorinated organoethynylxenon(II) salts [C4H9C≡CXe][BF4] and [(CH3)3CC≡CXe][BF4] were obtained in 20 to 40 % yield. All [RC≡CXe][BF4] salts are soluble in anhydrous HF (aHF) and the salts with R = C4H9 or R = (CH3)3C display sufficient solubility in the weakly coordinating solvents CH2Cl2 and PFP. The xenonium salts [RC≡CXe][BF4] were unambiguously characterised by their 1H-, 11B-, 13C-, 19F-, and 129Xe NMR spectra in solution.
