Chemical compound
This crystal of acetylferrocene was grown as part of an undergraduate course in UCL’s Department of Chemistry.

Acetylferrocene is the organoiron compound with the formula (C5H5)Fe(C5H4COMe). It consists of ferrocene substituted by one acetyl group on one of the cyclopentadienyl rings. It is an orange, air-stable solid that is soluble in organic solvents.

Preparation and reactions

Acetylferrocene is prepared by acetylation of ferrocene, usually with acetic anhydride]]:

(C5H52)Fe + Ac2O → (C5H5)Fe(C5H4Ac) + AcOH

The experiment is often used in the instructional laboratory to illustrate acylation as well as chromatographic separations.

Acetylferrocene can be converted to many derivatives, including reduction to the chiral alcohol. The oxidized derivative, acetylferrocenium, is used as a 1e-oxidant in the research laboratory.
