Will ferrocene undergo electrophilic aromatic substitution? Ferrocene has two structure 1 and 2.It is bonded to an aromatic ion cyclopentadienyl anion.Aromatic species such as benzene , cyclopentadienyl anion undergo electrophilic aromtic substitutions.

Then,will Ferrocene undergo  electrophilic aromtic substitution ?

Which conformer between 1 and 2, would preferentially undergo friedel crafts acylation reaction?
Due to the aromatic character of the cyclopentadienyl ligands, ferrocene can undergo electrophilic aromatic substitution reactions typical of aromatic compounds such as benzene. Ferrocene shows very high reactivity towards electrophiles, making it more closely comparable to phenol than to benzene, references and examples here and here.
