摘要：

1,4-Difluoro-1,4-diazoniabicyclo [2.2.2]octane salts, F-N-+(CH2CH2N+-F 2X(-) (2) where X(-) =BF4-, PF6-, FSO3-, CF3SO3-, have been synthesised by direct fluorination of 1:1 or 1:2 Lewis acid adducts of 1,4-diazabicyclo [2.2.2]octane with boron trifluoride, phosphorus pentafluoride or sulfur trioxide, and of 1,4-bis(trimethylsilyl)-1,4-diazoniabicyclo [2.2.2] octane ditriflate, respectively, in cold acetonitrile. The bis(tetrafluoroborate) salt (2; X(-) =BF4-) has also been obtained via fluorination of 1 -heptafluoro-n-butyryl-1,4-diazoniabicyclo [2.2.2] octane-trifluoromonoborane tetrafluoroborate.
