Description
Summary:[Display omitted] ► A new mesoporous silica supported Pd (II) catalyst had been successfully prepared. ► The catalyst showed high activity for Suzuki coupling reaction. ► The catalyst was easily recovered by simple filtration. ► The catalyst was reused for five cycles without evident loss in activity. A new functionalized SBA-16 catalyst immobilized palladium (II) has been synthesized. Inductively coupled plasma (ICP), small-angle X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen physical adsorption and Fourier transform infrared (FTIR) studies have been used to characterize the catalyst. The catalyst exhibited very high activity for Suzuki coupling reaction of aryl halides with arylboronic acids in EtOH/water under air atmosphere. On the other hand, the synthesized catalyst could be separated from the reaction mixture by simple filtration and reused up to five runs without significant loss in activity.
