Synthesis of 2,4,6-triarylpyridines catalyzed by a novel magnetic nanocomposite on the basis of carbon nanotube

Multicomponent reactions have been gained special attention in chemistry and pharmacology during the last decade, because they are simple, clean, quick and atom economic.1 Pyridines are widely used in various sciences including biology, biochemistry and medicinal chemistry.2 These compounds are used in chemical sensors3 and photochemical reaction initiators.4Herein, we wish to report a simple and efficient method for the synthesis of 2,4,6-triarylpyridines via the reactions of benzaldehydes, acetophenones and ammonium acetate in the presence of a new and recyclable magnetic nanocomposite. This nanocomposite has been made on the basis of carbon nanotubes and characterized by SEM, FT-IR, XRD, EDX and VSM analyses. Short reaction times, high yields of products, mild reaction conditions, easy work-up procedure, and the use of a highly efficient, non-corrosive, easy separable and reusable catalyst are noteworthy advantages of the present work
