Popis:	Ferrocenylbenzene (1) and ferrocenylbenzene tricarbonylchromium (2) were synthesized and characterized. NMR chemical shifts of benzene in 2 are shifted upfield compared to those of 1. We attribute the NMR spectrum of 2 to the reduced magnetic anisotropy effect of the benzene ring. Herein, we associate the electron density of the benzene ring in 1, 2, and p-ferrocenylaniline with the oxidation potential of the ferrocenyl group. The increased oxidation potential of ferrocene showed that the electron density of the benzene ring in 2 is reduced compared to that of 1, and the reduced oxidation potential of ferrocene indicates that the electron density of the benzene ring in p-ferrocenylaniline increased compared to that of 1. Therefore, ferrocene could be used as an electrochemical probe to predict the electron density of the benzene ring in 1, 2, and p-ferrocenylaniline.
