چکیده مقاله
In this study, a novel heterogeneous magnetic nanocatalyst, SnFe₂O₄@SiO₂@L@Pd, was designed and synthesized. The structure and properties of the nanocatalyst were thoroughly characterized using FT-IR, VSM, FE-SEM, EDS with elemental mapping, ICP-OES, XRD, TGA, and the structures of the products were confirmed by 1H/13C NMR and GC-MS. The results indicated that the catalyst exhibits uniform element distribution, high surface activity, strong magnetic behavior, thermal stability, and well-defined morphology. This nanocatalyst efficiently catalyzed the Stille cross-coupling reaction under mild and green conditions, providing the desired biaryl derivatives in 81-94% yield within 60-150 minutes. The Stille reaction is one of the most important methods for forming carbon–carbon bonds and synthesizing biaryl compounds, with wide applications in medicinal chemistry, bioactive materials, and the chemical industry. The reactions proceeded with high selectivity and reproducibility, and the magnetic properties of the catalyst allowed easy separation and reuse for at least five consecutive cycles without significant loss of activity. Therefore, SnFe₂O₄@SiO₂@L@Pd represents a robust, efficient, and recyclable nanocatalyst, providing a sustainable and green approach for the synthesis of biaryl compounds via the Stille reaction
