In the present work, Fe 3 O 4 @L‐Tyrosine‐Pd heterogeneous nanocatalyst was prepared by a simple and inexpensive procedure. The prepared nanocatalyst was characterized by Fourier transform infrared spectroscopy (FT‐IR), X‐ray Diffraction (XRD), energy‐dispersive X‐ray spectroscopy (EDS), inductively coupled plasma optical emission spectroscopy (ICP‐OES), scanning electron microscopy (SEM), Transmission electron microscopy)TEM(, X‐ray mapping, thermal gravimetric analysis (TGA), N 2 adsorption and desorption (BET) and vibrating sample magnetometer (VSM) techniques. Besides, it was employed as an efficent catalyst for C‐C cross coupling and S‐arylation reactions under green conditions. The optimized conditions for these reactions are described. The heterogeneous catalyst can be easily separated by applying a simple magnet and can also be reused in several consecutive runs without appreciable change in its catalytic activity.
