✦ Synopsis

Pyrrole is a five-membered aromatic heterocycle in which the nitrogen lone pair is delocalized over the p system of the ring. As a result of this p electron rich character, it reacts readily with electrophiles, but is not susceptible to nucleophilic attack. The g5-coordination of pyrrole or of the pyrrolyl anion to certain transition metal fragments activates the heterocycle toward nucleophilic substitution or addition reactions. In the pyrrolyl complexes

Cl, nucleophilic substitution reactions at the 2-position of the ring follow a pathway that involves hydrogen transfer from the ring to
