A simple, efficient and eco-friendly procedure has been developed using Selectfluor (15% mol) as a novel catalyst under ultrasound irradiation and solvent-free conditions for the synthesis of 2,4,5-triaryimidazole by a three-component, one-pot condensation of benzil, aryl aldehydes and ammonium acetate. The present methodology offers several advantages such as excellent yields, shorter reaction times (10-15 min) and environmentally benign milder reaction conditions and easy work-up.

A kinetic study of the chemiluminescent (CL) reaction mechanism of lophine-derived hydroperoxides and silylperoxides induced by a base and fluoride, respectively, provided evidence for the formation of a 1,2-dioxetane as a high-energy intermediate (HEI) o

A series of 2,4,5-trisubstituted imidazoles and 1,2-disubstituted benzimidazoles catalyzed by ZrO2-supported-β-cyclodextrin (ZrO2-β-CD) under solvent free conditions have been synthesized and characterized by spectral methods. The nanoparticles (ZrO2-β-CD), prepared by a simple one-pot-coprecipitation method and were characterized by PXRD, SEM, and TEM techniques. The nano (ZrO2-β-CD) particles were found to be an effective heterogeneous reusable catalyst for the effective synthesis of imidazoles and benzimidazoles under solvent free conditions and all of the synthesized derivatives were evaluated for their antibacterial activity against six bacterial strains.
Sulfamic acid as an efficient and cost-effective catalyst for the synthesis of 2,4,5-triarylimidazoles and 2-arylphenanthrimidazoles
Peng, Hua-Nan,Peng, Xiao-Ming,Zheng, Da-Gui,Yu, Fei,Rao, Min
experimental part, p. 223 - 226 (2012/03/10)
A simple and efficient synthesis of 2,4,5-triarylimidazoles and 2-arylphenanthrimidazoles was developed using the onepot, three-component condensation reaction of an aromatic aldehyde, benzil or 9,10-phenanthroquinone and ammonium acetate in refluxing ethanol in the presence of the catalyst sulfamic acid. 2011 · Copyright by Walter de Gruyter.
