Abstract
A magnetic nanocomposite based on graphene oxide was prepared. Fe3O4 nanoparticles were loaded on graphene oxide sheets and GO-Fe3O4 was covered by aniline-pyrrol copolymer to afford poly(Ani-co-Py)@GO-Fe3O4 nanocomposite. The poly(Ani-co-Py)@GO-Fe3O4 nanocomposite was characterized by FT-IR, TEM, VSM, TGA, XRD, and EDX techniques and applied in the synthesis of 2,4,6-triarylpyridines derivatives via four-component reaction of various benzaldehydes, acetophenones, and ammonium. The absence of solvent, high yields of products, short reaction times, mild reaction conditions, and easy work-up procedure in combination with non-toxicity, efficiency, high surface area, stability, cheapness, magnetic character, and reusability of the catalyst are noteworthy advantages of the present method.
