Synthesis of a wide range of biphenyl derivatives and symmetrical sulfides, using SnFe2O4@SiO2@P-Pd MNPs as a novel, efficient, green, and reusable catalyst

•This article discusses the emerging trends in catalytic biphenyl derivatives and symmetrical sulfides.•Nanocatalyst can be recovered and reused without metal leaching or decreasing catalytic activity.•The effects of different condition on the coupling reactions are emphasized.•The design of catalyst, based on the particle size, shape, surface composition, and morphology of catalysts elaborated. We have introduced the SnFe2O4@SiO2@P-Pd catalyst for the one-pot synthesis of biphenyl derivatives and symmetrical sulfides. For this purpose, SnFe2O4 nanoparticles were modified with Phenylalanine. The synthesized catalyst underwent characterization through BET, FT-IR, SEM, XRD, ICP, TGA, VSM, and EDX analyses. This novel approach offers the advantages of a recyclable heterogeneous catalyst, which can be easily separated from the reaction mixture using an external magnet, along with shorter reaction times, high product yields, and cost-effective, environmentally friendly conditions. The SnFe2O4@SiO2@P-Pd catalyst can be reused for up to five cycles without significant loss of catalytic activity. The results indicate that SnFe2O4@SiO2@P-Pd is an effective hybrid catalyst for synthesizing biphenyl derivatives and symmetrical sulfides. [Display omitted]
