Fe3O4-carbon spheres core-shell supported palladium nanoparticles:A robust and recyclable catalyst for suzuki coupling reaction
文献摘要:
Suzuki-Miyaura(S-M)is regarded the most powerful way for synthesis biaryls,triaryls,or incorporating of substituted aryl moieties in organic preparation by the cross-coupling of aryl boronic acid with aryl halides using the Pd catalyst.This work reports the combining of the hydrothermal and microwave-assisted protocol to convert the glucose to magnetic carbon spheres(Fe3O4-CSPs)decorated with Pd nanoparticles(NPs)as the catalyst for Suzuki-Miyaura cross-coupling reactions.The physicochemical properties in the produced composite were examined using FESEM,HRTEM,nitrogen isotherms,Raman spectroscopy,FTIR,XPS,and XRD.The as-fabricated composite Pd/Fe3O4-CSPs is mostly spherical with a core-shell structure and possesses a great surface area of 253.2 m2·g-1.Its catalytic performance demonstrates that the composite has excellent stability and high tolerance Suzuki-Miyaura cross-coupling reactions in 30 min at 80℃.Both activated and deactivated aryl halides provided excellent yield.The as-fabricated catalyst was recycled for up to four catalytic cycles without a substantial decline in performance.Moreover,this research offers a facile roadmap for synthesizing Pd/Fe3O4-CSPs compos-ites and promoting the practical implementation of Pd/Fe3O4-CSPs catalysts for organic transformation processes.
