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-Vis, Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) analysis. It was found that the GO-SB/Pd is an efficient catalyst in the Suzuki-Miyaura cross-coupling of phenylboronic acid with aryl halides. Moreover, the catalyst could be easily recycled and reused for several times without discernible loss in activity. (C) 2019 Elsevier Ltd. All rights reserved.
