Encapsulation of palladium chloride using 2‐formylbenzoic acid supported by Fe3O4 nanoparticles modified with SiO2 and propylamine, its characterization and its application for Suzuki coupling reaction

A magnetically separable heterogeneous nanocatalyst, Fe3O4@SiO2(CH2)3N―CH―Ar@Pd(0), was simply prepared and characterized using various techniques. The catalytic activity of this nanocatalyst was evaluated via the Suzuki–Miyaura cross‐coupling reaction of aryl halides with phenylboronic acid under various experimental conditions such as kind of base, solvent and temperature. This nanocatalyst is completely magnetically recoverable because of the superparamagnetic behaviour of Fe and can be reused with sustained selectivity and activity.
