This colourless solid is used in organic synthesis as a nitrosating agent.[1] NOBF4 is the nitrosonium salt of fluoroboric acid, and is composed of a nitrosonium cation, [NO]+, and a tetrafluoroborate anion, [BF4]−. ReactionsNitrosonium tetrafluoroborate may be used to prepare metal salts of the type [MII(CH3CN)x][BF4]2 (M = Cr, Mn, Fe, Co, Ni, Cu). The nitrosonium cation acts as the oxidizer, itself being reduced to nitric oxide gas:[2] M + NOBF4 + xCH3CN → [M(CH3CN)x](BF4)2 + NO With ferrocene the ferrocenium tetrafluoroborate is formed.[3] References1. ^{{ cite web | url = http://www.alfa.com/en/GP100W.pgm?DSSTK=A15806 | title = A15806 Nitrosonium tetrafluoroborate, 98% | work = Alfa Aesar website | accessdate = 2010-09-04 }} {{Tetrafluoroborates}}{{inorganic-compound-stub}}2. ^{{cite journal | doi = 10.1002/0471224502.ch2 | journal = Inorg.
