A simple, one-pot and copper-catalyzed coupling reaction for the construction of 1,2-disubstituted benzimidazole derivatives is described. Low-cost copper salt and weak base K3PO4 were utlized in this reaction. A variety of 1,2-disubstituted benzimidazoles were obtained in moderate to excellent yields.
