Abstract An operationally simple, efficient, and environmentally benign preparation of heteroaromatics such as thiazoles, imidazoles, and imidazo [1, 2-a] pyridines from the reactions of a polymer-supported [hydroxy (sulfonyloxy) iodo] benzene (2) with ketones or alcohols, followed by treatment with thioamides, benzamidine, and 2-aminopyridine, respectively, in the presence of potassium carbonate were successfully carried out.
