A series of (aroylcyclopentadienyl)rhenium tricarbonyls ((η5-RC6H4COC5H 4)Re(CO)3, R = H, o-CH3, p-CH3, p-OCH3, o-F, p-Cl) and their Cr(CO)3 ((η6-arene)Cr(CO)3) complexes have been prepared and characterized and studied by IR and 1H NMR spectroscopy. The carbonyl stretching frequencies of the Re(CO)3 group and the cyclopentadienyl proton resonances indicate π-electron withdrawal through the ligand system by the Cr(CO)3 group.
