Herein, we describe a highly efficient and eco-friendly protocol for the synthesis of benzimidazoles, benzothiazoles, and quinoxalines using VOSO₄ as a catalyst in ethanol. Use of nontoxic and recyclable catalyst, clean reaction profile, high yields, scalability, and broad substrate scope are the important practical features of the present protocol.
