An efficient and heterogeneous Pd-containing modified graphene oxide catalyst for preparation of biaryl compounds

Abstract

In this research, a novel palladium-containing modified-graphene oxide (GO-N2S2/Pd) catalyst is designed and synthesized for the Suzuki–Miyaura reaction. The prepared catalyst was characterized by different techniques, such as thermogravimetric analysis (TGA), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), energy-dispersive X-ray (EDX), Raman spectroscopy, X-ray diffraction (XRD), and inductively coupled plasma optical emission spectrometry (ICP-OES). The catalytic performance of the synthesized catalyst was evaluated in the Suzuki cross-coupling reaction of phenylboronic acid and aryl halides with K2CO3 as a base. Good recoverability and reusability of this heterogeneous catalyst at the end of the reaction were observed.
