Efficient and Green Synthesis of N‐aryl Pyrroles Catalyzed by Ionic Liquid [H‐NMP][HSO4] in Water at Room Temperature

A suitable and efficient method for the synthesis of N‐aryl pyrroles by using 2,5‐dimethoxy tetrahydrofuran and several primary aromatic amines in the presence of the catalytic amount of H‐NMP]HSO₄] under room temperature was described. This method has the advantages such as; easy reaction workup, absolutely separated of catalyst from the reaction mixture and smoothly recyclability of catalyst. In this reaction, N‐substituted pyrroles were obtained as desired products in excellent yields and short reaction times via green and one‐pot procedure.
