Abstract
In the present work, a palladium-based catalyst (Pd-DBA@NiFe2O4) supported on 3,5-diaminobenzoic acid functionalized was successfully prepared from NiFe2O4 NPs, via an inexpensive and simple procedure. This eco-friendly heterogeneous catalyst was characterized by X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), inductively coupled plasma atomic emission spectroscopy (ICP), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) techniques. Besides, it was employed as an efficient catalyst for C-C and the C–S cross-coupling under green conditions. High catalytic performance was demonstrated by this nanocatalyst under green conditions, and excellent yields of products were obtained in relatively short reaction times. The clean ligand-free protocol, devoid of hazardous chemicals, excellent yields in short reaction time, and the reusability of catalyst for several times are the key factors in the methodology. The synthesized solid catalyst can be reused and recovered for Six cycles without losing its catalytic activity.
