Nitrosonium tetrafluoroborate, also called nitrosyl tetrafluoroborate, is a chemical compound with the chemical formula NOBF4. This colourless solid finds use in organic synthesis as a nitrosating agent.
NOBF4 is the nitrosonium salt of fluoroboric acid, and is composed of a nitrosonium cation, , and a tetrafluoroborate anion, .
Reactions
Nitrosonium tetrafluoroborate may be used to prepare metal salts of the type 2 (M = Cr, Mn, Fe, Co, Ni, Cu). The nitrosonium cation acts as the oxidizer, itself being reduced to nitric oxide gas: With ferrocene the ferrocenium tetrafluoroborate is formed.
- M + NOBF4 + xCH3CN → (BF4)2 + NO
