Synthesis of 2,4,5-Tri substituted Imidazoles Using Nano-[Zn-2BSMP]Cl2 as a Schiff Base Complex and Catalyst

Abstract

Nano-Zn-[2-boromophenyl-salicylaldimine-methylpyranopyrazole]Cl2 nanoparticles (nano-[Zn-2BSMP]Cl2) as a Schiff base complex and catalyst was used for the preparation of 2,4,5-tri substituted imidazoles by the one-pot multi-component condensation reaction of benzil with various aromatic aldehydes and ammonium acetate at 80 °C under solvent-free conditions.
