Palladium CNC-pincer complex supported on magnetic nanospindles as a highly efficient and recyclable nanocatalyst in Mizoroki-Heck cross-coupling and reduction of nitroarenes

Fe3O4 nanospindles were synthesized through the hydrothermal method followed by thermal treatment. The composite of Fe3O4@SiO2 core-shell nanospindles was synthesized by the Stuber process via the hydrolysis of tetraethyl orthosilicate (TEOS) in the presence of Fe3O4 nanospindles. Palladium triazine-bridged bisimidazolium pincer complex was successfully supported on Fe3O4@SiO2 core-shell nanospindles. The magnetic nanospindles-supported palladium CNC-pincer complex was used as a practical and recyclable catalyst in the Mizoroki-Heck cross-coupling reaction and reduction of nitroarenes.
