Abstract
Ionic liquid mediated Friedel–Crafts acylation of the organometallic complex ferrocene can be performed in 1-ethyl-3-methylimidazolium halogenoaluminate melts, EtMeimI–AlCl3, as well as in the liquid clathrate formed upon addition of an excess of toluene to EtMeimI–AlCl3 affording solely the monoacylated product acetylcyclopentadienyl (cyclo- pentadienyl)iron(II) in good to excellent yields under the appropriate conditions.Keywords
