Specification
Magnetic Fe3O4 nanoparticles were functionalized with 3,4-dihydroxypyridine and then used as stable supports for palladium (Pd) to prepare reusable and efficient heterogeneous catalysts for catalyzing Suzuki cross-coupling reaction.
Synthesis procedure of high-efficiency catalyst Fe3O4/Py/Pd(0)
· The Fe3O4 MNPs powder (500 mg) was dispersed in 50 mL ethanol/water (volume ratio, 1 : 1) solution by sonication for 20 min, and 3,4-dihydroxypyridine (Py) (250 mg) was added to the mixture. The mixture was stirred for 5 h at 40 °C.
· The precipitated product was subjected to centrifugal separation, magnetic decantation separation and vacuum drying to obtain Fe3O4/Py compound.
· Fe3O4/Py (500 mg) was dispersed in CH3CN (30 mL) by ultrasonic bath. A solution of PdCl2 (30 mg) in 30 mL acetonitrile was added to the Fe3O4/Py dispersion for reaction.
· The obtained Fe3O4/Py/Pd(II) was separated by magnetic decantation and washed with CH3CN, H2O and acetone respectively.
· Reduction of Fe3O4/Py/Pd(II) with sodium borohydride. The final product Fe3O4/Py/Pd(0) was washed with water and ethanol and dried under vacuum at 40°C.
