Ligand
exchange reaction is one of the typical reactions of ferrocene. In this paper, ligand exchange reactions were carried out
between ferrocene and various
substituted benzenes using aluminum chloride catalysis. The product yields of the reactions with alkanoyl- and alkoxybenzenes were low because of
the coordination of aluminum chloride to the oxygens of the benzene
substituents. Comparing the reactions using o-
and p-dimethoxybenzene, the former was revealed to be less reactive; this is likely
due to the deviation of the π-electrons of its benzene ring being
larger.
