A Sustainable Microwave Protocol for the Synthesis of Benzimidazole Scaffolds

The green chemistry approach emphasizes reduced energy consumption, minimal solvent use, and safer reaction conditions, aligning with the principles of sustainability and environmental responsibility. Microwave irradiation, as a green synthetic tool, offers rapid, uniform heating, shorter reaction times, and enhanced efficiency, thus reducing the environmental footprint of chemical synthesis This work highlights the superiority of green microwave-assisted synthesis over traditional methods for the efficient and ecofriendly production of benzimidazole derivatives.In this study, four novel benzimidazole derivatives were synthesized using microwave reactor and one compound was synthesized by conventional method. In contrast, the green approach employed microwave-assisted synthesis, carried out under microwave irradiation for just 9–10 minutes, producing significantly higher yields than conventional synthesis.
