Description
Summary:In this work, an efficient epichlorohydrin–aminoguanidine-modified Fe 3 O 4 @SiO 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 3 O 4 @SiO 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 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. Graphical Abstract
