Acylated buckyferrocene and ruthenocene, Fe(η5-C60Me5)(η5-C5H4COR) (R = Me, Ph, and CHCHPh) and Ru(η5-C60Me5)(η5-C5H4COR) (R = Me and Ph), were obtained by FriedelâCrafts acylation of the parent buckymetallocenes with the corresponding acid chlorides and aluminum chloride in carbon disulfide at ambient temperature. The electron withdrawing and sterically hindered nature of the acyl groups were revealed by X-ray crystallography, infrared spectroscopy and electrochemical measurements. The possibility of further derivatizing the acylated products was illustrated by the conversion of the acetyl buckyruthenocene into the corresponding hydroxy and acetoxy compounds Ru(η5-C60Me5)(η5-C5H4CH(OH)Me) and Ru(η5-C60Me5)(η5-C5H4CH(OAc)Me).
