Acetylferrocene is the organoiron compound with the formula (C5H5)Fe(C5H4COCH3). It consists of ferrocene substituted by an 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 Friedel-Crafts acylation of ferrocene, usually with acetic anhydride (Ac2O):

Fe(C5H5)2 + Ac2O → (C5H5)Fe(C5H4Ac) + HOAc

The experiment is often conducted in the instructional laboratory to illustrate acylation as well as chromatographic separations.[2][3]

Acetylferrocene can be converted to many derivatives, e.g., reduction to the chiral alcohol (C5H5)Fe(C5H4CH(OH)Me) and precursor to vinylferrocene. The oxidized derivative, acetylferrocenium, is used as a 1e-oxidant in the research laboratory.[4]
