Vinylferrocene is the organometallic compound with the formula (C<sub>5</sub>H<sub>5</sub>)Fe(C<sub>5</sub>H<sub>4</sub>CH=CH<sub>2</sub>). It is a derivative of ferrocene, with a vinyl group attached to one cyclopentadienyl ligand. As the ferrocene analogue of styrene, it is the precursor to some polyferrocenes. It is an orange, air-stable oily solid that is soluble in nonpolar organic solvents.
Vinylferrocene can be prepared by the dehydration of ñ-hydroxylethylferrocene, which is obtained from acetylferrocene. It can also be made by a Wittig reaction of ferrocenecarboxaldehyde.
