摘要: A series of substituted imidazoles have been synthesized under solvent-free condition by grinding 1,2-diketone, aromatic aldehyde, and ammonium acetate in the presence molecular iodine as catalyst. The short reaction time easy workup make this protocol practically economically attractive are characterized NMR spectra, X-ray, mass, CHN analysis. Their antioxidant potential were evaluated using different vitro models namely, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical, superoxide anion, hydroxyl radical scavenging activities. antibacterial screening against Staphylococcus aureus, Escherichia coli, Klbesiella pneumoniae antifungal activity Aspergillus niger, flavus, Candida-6 also evaluated. Among all, dimethoxyphenyl substituent at N3 imidazole derivatives exhibited highest hydroxy anion activities, whereas fluorophenyl C2 activity.
