A magnetically retrievable mixed-valent Fe₃O₄@SiO₂/Pd⁰/Pd^II nanocomposite exhibiting facile tandem Suzuki coupling/transfer hydrogenation reaction.

ABSTRACT: Herein, we report a magnetically retrievable mixed-valent Fe₃O₄@SiO₂/Pd⁰/Pd^IINP (5) nanocomposite system for tandem Suzuki coupling/transfer hydrogenation reaction. The nanocomposite 5 was prepared first by making a layer of [Formula: see text] on [Formula: see text] followed by deposition of [Formula: see text] and sorption of [Formula: see text] ions successively onto the surface of Fe₃O₄@SiO₂NP. The nanocomposite was characterized by powder XRD, electron microscopy (SEM-EDS and TEM-EDS) and XPS spectroscopy techniques. The mixed-valent [Formula: see text] present onto the surface of nanocomposite 5 was confirmed by XPS technique. Interestingly, the mixed-valent nanocomposite Fe₃O₄
