- Synthesis and characterization of nano-copper ferrite as a magnetically separable catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free condition
-
The authors report herein, synthesis and characterization of nano-copper ferrite as a recoverable, ecofriendly, inexpensive, and readily available catalyst for efficient, simple, and green synthesis of multisubstituted imidazoles. Short reaction times, high yields, easy workup, and mild condition are the advantages of this protocol. The catalyst can be reused without evident loss of the catalytic activity. Characterization of the catalyst was performed fully by Fourier transform infrared spectra, X-ray diffraction, FESEM, electron dispersive X-ray, and vibration sampling magnetometer analyses.

- Study on the synthesis and structure-effect relationship of multi-aryl imidazoles with their fluorescence properties
-
In this paper, 23 multi-aryl imidazole derivatives were synthesized and identified by nuclear magnetic resonance, ultraviolet-visible and elemental analysis. At the same time, their ultraviolet-visible maximum absorption (λabmax), fluorescence emission maximum (λemmax) and quantum yields (Cyrillic capital letter eff) were measured. The relationships between the optical behaviors and structures for these compounds were assessed. The results show that the λmaxab and λmax em are red-shifted and the fluorescence Cyrillic capital letter eff are increased by the introduction of electron-withdrawing substituents and the increase in the planarity of multi-aryl imidazole molecules. The results also showed that the fluorescence quantum yields of the compounds containing two imidazole nuclei are double the corresponding mono-imidazole nucleus compounds. Copyright

- An expedient one-pot synthesis of highly substituted imidazoles using supported ionic liquid-like phase (SILLP) as a green and efficient catalyst and evaluation of their anti-microbial activity
-
An efficient method for the synthesis of imidazole derivatives by a three-component condensation of benzil or 9,10-phenanthrenequinone, aldehydes and ammonium acetate using supported ionic liquid-like phase (SILLP) catalyst under ultrasonic irradiation or classical heating conditions is reported. The present methodology offers several advantages, such as excellent yields, simple procedures, short reaction times, simple work-up and mild conditions. The catalyst is easily separated from the products by filtration and also exhibits remarkable reusable activity. These highly substituted imidazoles were also evaluated for their anti-microbial activity.
