===Redox chemistry – the ferrocenium ion===
{{main article|Ferrocenium}}
Unlike the majority of organic compounds, ferrocene undergoes a one-electron oxidation at a low potential, around 0.5&nbsp;V versus
. a [[saturated calomel electrode]] (SCE). This reversible oxidation has itself been used as standard in electrochemistry as Fc<sup>+</sup>/Fc&nbsp;= 0.64&nbsp;V versus the [[standard hydrogen electrode]]. Some [[electron]]-rich organic compounds (e.g., [[aniline]]) also are oxidized at low potentials, but only irreversibly. Oxidation of ferrocene gives the stable blue-colored iron(III) cation {{chem|Fe(C|5|H|5|)|2|+}} originally called ferricinium, but now more commonly ferrocenium (thes(contracted; show full)
