Procedure

1-benzoyl-4-fluoro-1,4-diazoniabicvclo[2.2.2]octane bis(tetrafluoroborate) 1,4-Diazabicyclo[2.2.2]octane N-oxide is prepared by the reaction of 1,4-diazabicyclo[2.2.2]octane with hydrogen peroxide as described by Farkas in J. Chem. Eng. Data (1968) 13, 278. 1,4-Diazabicyclo[2.2.2]octane N-oxide (12.8 g, 10 mmool) in THF (100 mL) is reacted with benzoyl chloride (14 g, 10 mmol) until the reaction is complete by TLC. The reaction is evaporated, diluted with acetonitrile (100 mL) and sodium tetrafluoroborate (40 g, 20 mmol) added. The solution is stirred overnight at room temperature and then filtered to remove all undissolved salts. The filtrate is evaporated to afford 1-benzoyl-4-aza-1-azoniabicyclo[2.2.2]octane tetrafluoroborate.
