Abstract:
The replacement of xenon(+) by iodine in reactions of alkenylxenonium(II) salts [RCF=CFXe]Y (R = cis-C2F5, trans-H) and alkynylxenonium(II) salt [C3F7C CXe][BF4] with NaI in anhydrous HF (aHF) occurred regiospecifically. At -60 degrees C the substitution of xenon(+) by bromine in the perfluorinated salts [cis-CF3CF=CFXe]Y and [trans-C4F9CF=CFXe]Y proceeded regio-and stereospecifically with NaBr in aHF, but at a higher temperature and after a longer time the treatment of[ciS-C2F5CF=CFXe]Y with NaBr, KBr, or [NBu4]Br in aHF gave mixtures of cis-and trans-perfluorobut-1-enyl bromides. The reaction of [C3F7C CXe][BF4] with NaBr in aHF at -65 degrees C gave only 48% of C3F7C CBr and was accompanied by a mixture of bromine-containing related olefins. Reaction pathways to the main product are discussed.
