| Abstract: | Superparamagnetic nanometer Fe3O4 was prepared by hydrothermal method,and it was supported on palladium catalyst after its surface was modified with hydroxyl group.The magnetic nanoparticle supported palladium catalyst was applied in the Suzuki cross-coupling reaction of phenyloboricacid and bromobenzene,and its catalytic activity and recycling effect was examined.The results indicated that the conversion of bromobenzene was 92.7 % under the reaction conditions such as the reaction time 2 h,and the reaction... |
