'''Acetylferrocene''' is the ] with the formula (C<sub>5</sub>H<sub>5</sub>)Fe(C<sub>5</sub>H<sub>4</sub>COCH<sub>3</sub>). It consists of ] substituted by an ] on one of the ] rings. It is an orange, air-stable solid that is soluble in organic solvents. |
|
'''Acetylferrocene''' is an ] compound based on ] with one ] added to the ] ring. It is mainly used in military or space field as an additive in rocket propellant, to promote the burning rate.<ref name="use">{{cite web|url=http://watson-int.com/key-products/product-details/14.html|title=Use of Acetylferrocene|publisher=Watson International Ltd|accessdate=2011-07-20}}</ref> |

==Preparation and reactions== |
|
|
Acetylferrocene is prepared by ] of ferrocene, usually with ] (Ac<sub>2</sub>O): |
|
|
:Fe(C<sub>5</sub>H<sub>5</sub>)<sub>2</sub> + Ac<sub>2</sub>O → (C<sub>5</sub>H<sub>5</sub>)Fe(C<sub>5</sub>H<sub>4</sub>Ac) + HOAc |
|
|
|
|
|
The experiment is often conducted in the instructional laboratory to illustrate ] as well as chromatographic separations.<ref>Bozak, R. E. "Acetylation of ferrocene: A chromatography experiment for elementary organic laboratory" J. Chem. Educ., 1966, volume 43, p 73.{{doi|10.1021/ed043p73}}</ref><ref>Donahue, C. J., Donahue, E. R., "Beyond Acetylferrocene: The Synthesis and NMR Spectra of a Series of Alkanoylferrocene Derivatives", Journal of Chemical Education 2013, volume 90, pp. 1688. {{doi|10.1021/ed300544n}}</ref> |

Acetylferrocene can be converted to many derivatives, e.g., reduction to the chiral alcohol (C<sub>5</sub>H<sub>5</sub>)Fe(C<sub>5</sub>H<sub>4</sub>CH(OH)Me) and precursor to ]. The oxidized derivative, acetyl], is used as a 1e-oxidant in the research laboratory.<ref>Connelly, N. G., Geiger, W. E., "Chemical Redox Agents for Organometallic Chemistry", Chem. Rev. 1996, 96, 877. {{doi|10.1021/cr940053x}}</ref> |
