AIM AND OBJECTIVE: One of the principles of green chemistry is using inexpensive reagents and catalysts to design green route for synthesis of organic compounds. Recently magnetic nanoparticles have provided a considerable merits. In this study, hollow Fe3O4@Dopamine-SO3H has been successfully applied for the green synthesis of tetrahydrobenzo[b]pyrans and spirooxindoles via one-pot multi-component reaction. MATERIALS AND METHODS: Chemical reagents were purchased from Merck and Aldrich. Melting ...

This paper describes a novel and effective approach to fabricate the core–shell Fe3O4@PANI-SO3H urchin-like morphology in a self-assembly method as nano-magnetic solid acid catalyst. The Fe3O4@PANI microspheres were synthesized via an in situ surface polymerization of aniline monomer in an acidic condition, using ammonium persulfate as the oxidant. It was found that upon sulfonation of polyaniline (PANI), the morphology changes to morphology similar to urchin confirming the transmission electron...

Abstract Development of efficient, inexpensive and recyclable catalysts for a reaction under mild and green reaction conditions is still a very marvelous topic. In this work, diphenyl diselenide stabilized on magnetic chitosan as a novel, highly efficient, ecologically safe, cost-effective and magnetically recoverable heterogeneous nano-biocatalyst was prepared and characterized by different techniques, such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravi...

Abstract In the present study diselenide stabilized on silica coated Fe 3 O 4 magnetic nano particles as a novel, highly efficient and magnetically retrievable heterogeneous catalyst was designed, synthesized and introduced. Full characterization of the newly prepared magnetic nanocatalyst was authenticated using several physico-chemical characterization techniques such as Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDX...

A novel magnetic catalyst-immobilized nano-palladium was efficiently prepared via a (2 + 3) cycloaddition pathway and characterized with different analyses, including FT-IR, FE-SEM, EDS, XRD, TEM and VSM methods. Also, topological and NBO analysis of a simple model of the catalyst with the M06/6-311 g(d,p)-LANL2DZ model chemistry have been introduced. In addition, the catalytic pursuit of this novel magnetic nanocatalyst was successfully evaluated in Sonogashira and Heck cross-coupling reactions...

ABSTRACTThe authors report herein, synthesis and characterization of nano-copper ferrite as a recoverable, eco-friendly, inexpensive, and readily available catalyst for efficient, simple, and green synthesis of multi-substituted 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 infrar...
