Synthesis of 2,4,5-triaryl-1H-imidazoles using a potent, green and reusable nano catalyst (FHS/SiO2)
A simple, green and efficient method for synthesis of 2,4,5-trisubstituted imidazoles is described via three-component cyclocondensation of benzil or benzoin, aldehyde and ammonium acetate by using the nano SiO2-supported ferric hydrogen sulfate (FHS/SiO2), as a catalyst, under solvent-free conditions. The nano SiO2 support and catalyst were characterized by X-ray diffraction (XRD), transmissio...

متن کاملDesign, preparation and characterization of a novel BiFeO3/CuWO4 heterojunction catalyst for one-pot synthesis of trisubstituted imidazoles
In this work a novel heterojunction catalyst have been synthesized and employed as a highly efficient catalyst for one-pot synthesis of substituted imidazoles. Analytical methods including Fourier transform infrared (FT-IR), diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), Energy- dispersive X-ray spectroscopy (EDX), Scanning electron microscopy (SEM) and Vibrating Sample Magnom...
متن کاملKaolin-SO3H as an efficient catalyst for one-pot synthesis of 1,2,4,5-tetrasubstituted imidazoles
Kaolin-SO3H as a new solid acid is prepared via reaction of kaolin and chlorosulfonic acid. This natural based catalyst is very inexpensive and easy available. Imidazoles are an important class of heterocycles being the core fragment of different natural products and biological systems such as anti-allergic, anti-inflammatory, analgesic, antifungal, antimycotic, antibiotic, antiulcerative, anti...
