Description
Summary:In this paper, a novel nanocatalyst is designed and synthesized based on the immobilization of palladium acetate onto the organically modified magnetic iron oxide nanoparticles. γ-Fe2O3@SiO2(CH2)3-HPBM-Pd is synthesized thorough the functionalization of γ-Fe2O3@SiO2 nanoparticles by 2-(2′-hydroxyphenyl)-benzothiazole (HPBM) functionality, which is used as an efficient ligand for palladium ions. The nanocatalyst is characterized by several characterization techniques, including TEM, SEM, DLS, FT-IR, NMR, VSM, and ICP analysis. The catalytic activity of γ-Fe2O3@SiO2(CH2)3-HPBM-Pd nanoparticles is evaluated in the Mizoroki-Heck and Suzuki-Miyaura cross-coupling reactions. The nanocatalyst showed very good activity toward the mentioned reactions in water in the presence of 0.20 mol% of the Pd catalyst. In addition, the catalyst showed to be highly reusable and the catalyst turnover number calculated to be 4600 in 10 sequential runs.
