摘要: Abstract The polystyrene-supported Pd(II) N , -dimethylethylenediamine complex was prepared and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), atomic absorption (AAS), thermal analysis (TG-DTA). This heterogeneous catalyst works efficiently for the Suzuki–Miyaura coupling of arylboronic acids with aryl bromides in aqueous medium. effect base, additives C–C reactions were reported. Further, can be easily recovered quantitatively simple filtration reused up to five times without significant loss its catalytic activity.
