Description

General description

Ferrocenium tetrafluoroborate [FeCp₂][BF₄] is one of the commonly employed ferrocenium salts within chemical synthesis. Ferrocenium salts are commonly used as Lewis acid catalysts, one-electron oxidants, and electron donors.[1]

Application

Ferrocenium tetrafluoroborate serves as:

• an oxidizing agent in the synthesis of the monocationic Co(II)complex [CpCo(azpy)]⁺
• a Lewis acid catalyst in epoxide ring opening and to activatethe carbonyl group for addition or cycloadditions reactions
• an oxidizing agent when used in conjuntion with a Cl^-source[2]
• a reversible redox reagent between stannole dianion and bistannole-1,2-dianion[3]
