| Abstract: | The magnetic nano-beads of Fe3O4/polystyrene with core/shell structure were used as catalyst carriers and its surface was modified with high active ligand of bulky N-heterocyclic carbine via Friedel-Crafts reaction. Suzuki-Miyaura coupling reaction was used to evaluate the catalytic properties of the obtained catalysts. It indicated that the catalyst could be easily separated and showed extremely high activity when brombenzene was employed as starting material. It showed good catalytic activity to the chlorobenzene, and the good reusability was also found for these magnetic catalysts. |
