Eco-Friendly Synthesis of 1H-benzo[d]imidazole Derivatives by ZnO NPs Characterization, DFT Studies, Antioxidant and Insilico Studies

Benzimidazoles are classified as a category of heterocyclic compounds. Molecules having benzimidazole motifs show promising utility in organic and scientific studies. A series mono-substituted benzimidazoles were synthesized by ZnO-NPs via cyclocondensation between substituted aromatic aldehydes o-phenylene diamine. The compounds characterized compared with the traditional methods. nano-catalyzed method displayed higher yield, shorter time recyclable catalyst. DFT study antioxidant activity investigated for benzo[d]imidazole derivatives. Compound 2a exhibited highest among tested We focused on catalytic ZnO synthesis structures goal stimulating further progress this field. superiorities procedure high yield product, low amounts catalyst short reaction time.
