Abstract

One-Pot Synthesis of New Benzimidazole Derivatives Promoted by Potassium Carbonate. -An efficient method for the synthesis of new benzimidazoline derivatives (IV) (18 examples) via a one-pot three-component reaction of phenylenediamines with aromatic aldehydes and Ar 2O is given. However, aryl aldehydes bearing electron-releasing substituents do not work in this reaction. -(ZHANG*, D.-L.; XUE, M.-W.; ZHOU, H.; YANG, J.-J.; LI, J.; LIU, S.-X.; Heterocycles 89 (2014) 12, 2777-2785, http://dx.
