  2. For five - membered, electron - rich heterocycles, the utility of electrophilic substitutions is much greater. Heterocycles such as pyrrole, thiophene and furan undergo a range of electrophilic substitutions with great ease, at either type of ring position, but with a preference for attack adjacent to the heteroatom – at their a- positions.
