Ferrocenium tetrafluoroborate (original) (raw)
Ferrocenium tetrafluoroborate is an organometallic compound with the formula [Fe(C5H5)2]BF4. This salt is composed of the cation [Fe(C5H5)2]+ and the tetrafluoroborate anion (BF−4). The related hexafluorophosphate is also a popular reagent with similar properties. The cation is often abbreviated Fc+ or Cp2Fe+. The salt is deep blue in color and paramagnetic.Ferrocenium salts are sometimes used as one-electron oxidizing agents, and the reduced product, ferrocene, is inert and readily separated from ionic products. The ferrocene–ferrocenium couple is often used as a reference in electrochemistry. The standard potential of ferrocene-ferrocenium is 0.400 V vs. the normal hydrogen electrode (NHE) and is often assumed to be invariant between different solvents.

(en) Le tétrafluoroborate de ferrocénium est un composé organométallique de formule chimique [Fe(C5H5)2]BF4. Il s'agit d'un sel paramagnétique de couleur bleu marine constitué du cation ferrocénium [Fe(C5H5)2]+ et de l'anion tétrafluoroborate BF4−. Ses propriétés sont semblables à celles de l'hexafluorophosphate de ferrocénium [Fe(C5H5)2]PF6, réactif apparenté couramment utilisé. Le cation est souvent abrégé Fc+ ou Cp2Fe+. Les sels de ferrocénium sont des oxydants à un électron tandis que le ferrocène, qui correspond au ferrocénium réduit, est relativement inerte et facilement séparé des produits ioniques. Le couple ferrocène/ferrocénium est souvent utilisé comme référence en électrochimie. Son potentiel d'oxydoréduction est de 0,400 V par rapport à l'électrode standard à hydrogène et est généralement considéré comme invariant entre différents solvants. Le tétrafluoroborate de ferrocénium peut être acheté dans le commerce. Il peut également être préparé en oxydant du ferrocène à l'aide de sels ferriques puis en ajoutant de l'acide tétrafluoroborique HBF4. On peut également utiliser une grande variété d'autres oxydants, comme le tétrafluoroborate de nitrosyle (NO)BF4. On connaît de nombreux sels de ferrocénium analogues.

Questo sale è composto dal catione ferrocenio [Fe(C5H5)2]+, spesso abbreviato come Fc+, e dall'anione tetrafluoroborato BF4–. Il sale con l'anione esafluorofosfato è anche comune, e ha proprietà simili. Il sale è di colore blu scuro. Il catione ferrocenio è paramagnetico ed è piuttosto reattivo, essendo una specie a 17 elettroni. Sali di ferrocenio sono usati come ossidanti monoelettronici; per riduzione si forma ferrocene, prodotto neutro e inerte che si può facilmente separare dai reattivi ionici. La coppia redox ferrocenio/ferrocene è spesso usata come standard in elettrochimica. In soluzione di acetonitrile in NBu4PF6 0,1 M il potenziale di riduzione della coppia Fc+/0 è +0,641 V rispetto all'elettrodo standard a idrogeno.

Het verwante hexafluorfosfaat heeft vergelijkbare eigenschappen. Het kation wordt vaak afgekort tot Fc+. De verbinding heeft een donkerblauwe kleur en is paramagnetisch. Ferroceniumzouten worden soms toegepast als één-elektronoxidatoren. Het reactieproduct, ferroceen, is vaak eenvoudig van de andere reactieproducten te scheiden. Het ferroceen/ferrocenium-koppel wordt in de elektrochemie toegepast als referentie-elektrode. In acetonitril heeft (met naast ferrocenium en ferroceen 0,1 mol/L NBu4PF6) het koppel Fc+/0 een E°-waarde van +0,641 V ten opzichte van de standaard-waterstofelektrode.
