Palladium-coated thiourea core-shell nanocomposite as a new, efficient, and magnetic responsive nanocatalyst for the Suzuki-Miyaura coupling reactions

Abstract

In this research, according to the important aspects of palladium components in conducting Suzuki-Miyaura coupling reactions and formation of biphenyl compounds, magnetic responsive palladium/thiourea nanocomposite as a new magnetic nanocatalyst was designed, synthesized, and characterized using FT-IR, EDX, FE-SEM, and VSM analyses. The catalytic performance of this new nanocomposite with magnetic susceptibility was evaluated in the Suzuki-Miyaura coupling reaction. Based on the functionalized surface of Fe3O4 magnetic cores with SiO2, CPTMS, thiourea shells, and especially Palladium ions shell, the formation of biphenyl derivatives in a green and eco-friendly reaction condition was highlighted.
