Like pyrrole, indole has both weakly basic and also weakly acidic … Indole, benzopyrrole, is a yellow crystalline powder with unpleasant aroma. It has the pyrrole ring (five-membered unsaturated ring structure composed of four carbon atoms and one nitrogen atom) which is fused to benzene ring. There are tautomerer called indolenine (unsubstituted 3H-indole) and structural isomer, isoindole. But they are unstable. A shockwave experiment on indole (2,3-benzopyrrole) was performed in the temperature range 800–1400°C [9]. Three main pyrolysis products were found as the results of the opening of the pyrrole ring: phenylacetonitrile and 2- and 3-methylbenzonitrile.
