Graphene oxide supported Schiff–base/palladium complex: An efficient and recoverable catalyst for Suzuki-Miyaura coupling reaction

In the current research, preparation, characterization and catalytic application of a novel Schiff-base/Pd complex immobilized onto graphene oxide (GO−SB/Pd) are investigated. The GO−SB/Pd was characterized using Fourier transform infrared spectroscopy, thermal gravimetric analysis, diffuse reflectance UV–visible, Raman spectroscopy, scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis. It was found that the GO−SB/Pd can act as an efficient catalyst in the Suzuki–Miyaura cross−coupling of phenylboronic acid with aryl halides. Moreover, the catalyst could be readily recycled and reused for several times without discernible loss in activity.
