Abstract

A novel sulfonic-functionalized ionic liquid, C₃N₄ (C₃N₄-SO₃H (IL)), was prepared and its structure was characterized using FTIR, TEM, XRD, CHNS elemental analysis and FESEM-EDX mapping. Catalytic activity of the liquid was studied for the syntheses of pyrazolo[3,4-b]pyridine and bis(indolyl)methane derivatives under moderate conditions. The catalyst was demonstrated to be reused at least 5 runs without considerable decrease in its activity. Some of the important advantages of the methodology were proved to be good yields, easy work-up, short reaction time and broad scope of substrates.
