acetylation of ferrocene

Summary

The Friedel-Crafts acylation reaction of ferrocene involves the addition of the acylium cation to one of the carbon atoms on the ring, followed by loss of a proton (to solvent). 1 The acylium cation is produced from acetic anhydride, which also serves as a solvent for this reaction. 1 This reaction is known as acetylation of ferrocene.
