One Pot Multicomponent Green Synthesis of Triaryl Imidazoles Catalysed by Nano Nickel Cobalt Ferrite

Abstract

2,4,5-Triaryl imidazoles have been developed by the reaction of benzil, ammonium acetate and aldehydes in ethanol using magnetically reusable nano nickel cobalt ferrite (NiCoFe 2 O 4). It is a simple, highly efficient, three component one-pot green synthetic method. The advantages of this procedure are high product yields, easy operational method, mild conditions, magnetically recoverable and re-usable catalyst. Most important to all, the catalyst can be recovered by simple filtration and reusable up to five cycles without losing its catalytic activity.

Preparation and Characterization of NiCoFe2O4 Nanoparticles as an Effective Catalyst for the Synthesis of Trisubstituted Imidazole Derivatives Under Solvent-free Conditions

“…The structure of the products was characterized by spectroscopic data such as IR, 1 H NMR and melting point, and these compounds agreed with those of the authentic samples. 40,[50][51][52][53][54][55][56][57] In the FT-IR spectrum of 2(4-methoxyphenyl)-4,5diphenyl-1H-imidazole, the peak observed at 3464 cm -1 is associated with the N-H stretching bond of the amine group. The C=N peak with average intensity appears in the region of 1503 cm -1 .…”
