Boron trifluoride → HCID 19048048, compound

Participants

Reaction Steps

A solution of 1-sulfo-4-aza-1-azoniabicyclo[2.2.2]octane tetrafluoroborate (28 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 DME and dried to afford 1-fluoro-4-sulfo-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate).
