Magnetically recyclable Schiff-based palladium nanocatalyst [Fe3O4@SiNSB-Pd] and its catalytic applications in Heck reaction

A magnetically separable palladium nanocatalyst has been synthesized through the immobilization of onto 3-aminopropylphenanthroline Schiff based functionalized silica coated superparamagnetic Fe3O4 nanoparticles. The (Fe3O4@SiNSB-Pd) was fully characterized using several spectroscopic techniques, such as FT-IR, HR-SEM, TEM, XRD, ICP, and XPS. microscopic image showed spherical shape morphology had an average size 150 nm. Pd-nanoparticles exhibited 3.5 ± 0.6 successful functionalization Fe3O4@SiNSB-Pd identified by FT-IR spectroscopy appearance species in confirmed XRD analysis. While XPS utilized for determination chemical oxidation state Fe3O4@SiNSB-Pd. Several activated deactivated arene halides olefines were employed Mizoroki-Heck cross-coupling reactions presence Fe3O4@SiNSB-Pd, each which produced respective products with excellent yields. shows good reactivity reusability up to seven consecutive cycles.
