Description
Summary:In this work, an efficient epichlorohydrin-aminoguanidine-modified Fe.sub.3O.sub.4@SiO.sub.2 magnetic nanoparticles (FeS@EP-AG-Pd) with highly dispersed Palladium nanoparticles (Pd NPs) was reported for Suzuki reaction in water. After preparation of Fe.sub.3O.sub.4@SiO.sub.2 (FeS), special epichlorohydrin-aminoguanidine linker as a ligand with high content of heteroatoms was covalently bonded onto the FeS MNPs to increase their electron density. Pd.sup.II ions were then loaded on surface of FeS@EP-AG MNPs and reduced for achieving the uniformly dispersed Pd NPs. FeS@EP-AG-Pd MNPs were performed in Suzuki reaction as an efficient catalyst in water as a green non-toxic solvent. Magnetically separable and recyclable FeS@EP-AG-Pd MNPs were then fully characterized by FTIR, SEM, TEM, TGA, VSM, XRD, and ICP-OES. The heterogeneous catalyst could also easily be recovered and reused with no loss of activity over 6 cycles.
