Chemical compound

Ferrocenium tetrafluoroborate is an organometallic compound with the formula BF4. This salt is composed of the cation and the tetrafluoroborate anion (BF4). The related hexafluorophosphate is also a popular reagent with similar properties. The cation is often abbreviated Fc. The salt is deep blue in color and paramagnetic.

Ferrocenium salts are sometimes used as one-electron oxidizing agents. The product of the oxidation, ferrocene, is inert and readily separated from ionic products. The ferrocene/ferrocenium couple is often used as a reference in electrochemistry. In acetonitrile solution that is 0.1 M in NBu4PF6, the Fc couple is +0.641 V vs the normal hydrogen electrode.

Preparation

Commercially available, this compound may be prepared by oxidizing ferrocene with nitrosyl tetrafluoroborate.
