|Section2= |Section3= }} 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.〔(【引用サイトリンク】 A15806 Nitrosonium tetrafluoroborate, 98% )〕 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: : M + NOBF4 + ''x''CH3CN → ()(BF4)2 + NO With ferrocene the ferrocenium tetrafluoroborate is formed.
