چکیده مقالهThe carbon–carbon cross coupling reactions through transition-metal-catalyzed processes has been significantly developed for their important synthetic applications. A novel and fantastic nickel-based catalyst supported on bis (propyl malononitrile) (NiFe2O4@SiO2-BPMN-Ni) was easily prepared and evaluated as heterogeneous nanocatalyst in Suzuki cross coupling reaction of various aryl halides and phenylboronic acid. The catalyst prepared and characterized by using fourier transform infrared (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), thermo gravimetric analysis (TGA) and vibrating sample magnetometer (VSM) techniques. Compare to the previous works, this procedure have advantages such as easy workup, high yields of products, environmentally benign and short reaction times. The catalyst can be separated by external magnet and reused six times without any significant loss of activity which is an additional sustainable characteristic of this method. The products have been confirmed by spectroscopic and physical data such as; IR, 1H NMR, and melting point.
