Abstract: 
Heteropoly acid supported on silica gel (H3PW12O40/SiO2) is easily used as a heterogonous, reusable and efficient catalyst for the synthesis of N-substituted, 2- and 3-unsubstituted pyrroles in solution or under solvent-free microwave irradiation. The catalyst can be easily recovered and reused for several times without loss of activity.
