It is shown that the cyclopentadienide anion can undergo an electrophilic substitution. In methylation reactions it was possible to stop the reaction at the intermediate 5-substituted cyclopentadiene stage. In the methylcyclopentadienide anion, the methyl group directs an electrophile to the adjacent carbon atom.
