Pyrrole is an aromatic heterocyclic amine with a five-membered ring structure, commonly found as a light yellow liquid with a chloroform-like odor at room temperature.
Pyrrole is used in organic synthesis, and polymer production, as a corrosion inhibitor for steel, an electrolyte in capacitors, and a solvent. It's also integral in synthesizing porphyrins, which have applications in pressure sensors, solar cells, and organic ELs.
With a melting point of -11°F and a boiling point of 256.6°F, pyrrole is insoluble in water but soluble in organic solvents. It's less basic compared to pyridine due to the delocalization of the nitrogen atom's lone electron pair.
The molecular formula of pyrrole is C4H5N, with a molecular weight of 67.09 and a density of 0.967 g/cm3.
Pyrrole can be produced by reacting furan and ammonia using alumina as a catalyst. Various other methods include Hantzsch's, Knoll's, and Paal-Knorr synthesis, yielding substituted pyrroles.
While pyrrole displays aromatic reactivity similar to benzene and aniline, it undergoes alkylation, acylation, and polymerization under specific conditions.
The hydrogen atom bonded to nitrogen in pyrrole is slightly acidic, allowing for deprotonation and subsequent reactions with electrophiles.
Reduction of pyrrole leads to the formation of pyrrolidine and pyrroline, essential in various chemical syntheses.
