Boron trifluoride → 1-Acetoxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)

Participants

Reaction Steps

A solution of 1-acetoxy-4-aza-1-azoniabicyclo[2.2.2]octane tetrafluoroborate (25.8 g, 10 mmole) and boron trifluoride gas (6.7 g, 10 mmole) in acetonitrile (125 mL) was cooled to 8° C. and treated with a mixture of fluorine in nitrogen (10% V/V, 12 mmole). The reaction was evaporated, the remaining solid washed with dimethoxyethane and dried to afford 1-acetoxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate).
