Full TextAbstract
Herein we report the synthesis of a magnetically separable Fe3O4@Silica-Threonine-Pd0 magnetic nanoparticles with core-shell structure. After synthesis of Fe3O4@Silica, Threonine amino acid as an efficient stabilizer/ligand was bonded to the surface of Fe3O4@Silica. Then, palladium nanoparticles (Pd NPs) were generated on Threonine modified catalyst. Threonine stabilizer help to generation of Pd NPs in small size (below than 4 nm) with high dispersity and uniformity. Magnetically separable Fe3O4@Silica-Threonine-Pd0 nanocatalyst was full characterized by FT-IR, SEM, TEM, TGA, VSM, XRD, and ICP-OES. Efficiently, this nanocatalyst catalyzed Heck cross-coupling reaction of variety of substrates in water medium as a green, safe and inexpensive solvent at 80 °C. The Fe3O4@Silica-Threonine-Pd0 MNPs were used at least for 8 successful consecutive runs with only 0.05% of Pd leaching
