multicomponent reactions synthesis of triaryl-1h imidazoles using reductive-oxidative reactions by mno2-feso4 as a catalyst

The study's chief purpose is to investigate multicomponent reactions synthesis of triaryl- 1h imidazoles using reductive-oxidative reactions by mno2 - feso4 as a catalyst.some novel substituted imidazoles have been synthesized using mcrs, one-pot synthesis, and mno2/feso4 as a catalyst; the method involves the reaction of benzil, aromatic aldehyde, and ammonium acetate in the presence of mno2/feso4 as a reductive-oxidative catalyst under mild conditions. the obtained compounds were nontoxic, excellent yields, and environmentally friendly. the compounds were elucidated using ir and 1h-nmr spectra. to satisfy the aim of the study, reactions have been performed simply by mixing 1,2-diketone with an aldehyde and ammonium acetate in the presence of the catalytic reagent of mno2/feso4. the mixture was prepared by ground them together in a mortar with a pestle at room temperature for several minutes; after that, they purified by column chromatography, 2,4,5-triaryl substituted imidazole derivatives were obtained in excellent yields.
