2. Introduction
Pyrrole is an important five membered
heterocyclic compound possessing a
nitrogen atom as hetero atom.
plays important role in the chemistry of
living organisms.
The essential structural feature of
chlorophyll and heme is porphyrin,
which consists of four Pyrrole rings
held together by bridges.
