摘要

Abstract

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 (Fe

-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/Fe

-CSPs is mostly spherical with a core–shell structure and possesses a great surface area of 253.2 m

·g

. 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 perfor

mance. Moreover

this research offers a facile roadmap for synthesizing Pd/Fe

-CSPs composites and promoting the practical implementation of Pd/Fe

-CSPs catalysts for organic transformation processes.
