摘要：

Here a novel Pd supported polymeric magnetic nanoparticles with urea-pyridine bridge (denoted as Fe3O4@/Urea-Pyridine/Pd) was synthesized and characterized. The Fe3O4@/Urea-Pyridine/Pd nanocatalyst was synthesized via a four steps process by using Fe3O4 nanoparticles, 3-(triethoxysilyl) propylisocyanate (TESPIC), 2,6 bis(propyl-triethoxysilylureylene) pyridine (BPS) and palladium chloride. The synthesized polymeric Fe3O4@/Urea-Pyridine/Pd nanocatalyst was analyzed through different analytical techniques, including FT-IR, NMR, XRD, VSM, TGA, DTA, ICP, FESEM, EDX, and BET. The described palladium supported polymeric magnetic nanoparticles with urea-pyridine bridge (Pd-MNPs) was used for the C-C and C-N coupling of phenylboronic acid with various amines and aryl halides in DMF as well as Sonogashira and Suzuki reactions in aqueous solution. Also, the Fe3O4@/Urea-Pyridine/Pd nanocatalyst exhibited high structural stability and excellent recyclability.
