Реферат: The perfluorinated organoethynylxenon(II) salts, [RC=CXe][BF4] [R = CF3, C3F7, (CF3)(2)CF, 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 degrees C and isolated in 30-98 % yield. Similarly, the non-fluorinated organoethynylxenon(II) salts [C4H9C=CXe][BF4] and [(CH3)(3)CC=CXe][BF4] were obtained in 20 to 40 % yield. All [RC=CXe][BF4] salts are soluble in anhydrous HE (aHF) and the salts with R = C4H9 or R = (CH3)(3)C display sufficient solubility in the weakly coordinating solvents CH2Cl2 and PFP. The xenonium. salts [RC=CXe][BF4] were unambiguously characterised by their H-1-, B-11-, C-13-, F-19-, and Xe-129 NMR spectra in solution.
