Abstract

A hierarchical core–shell–satellite structured composite system Fe3O4@MS–NH2@Pd, which was composed of Pd nanoparticles well-dispersed on an amino group functionalized mesoporous silica (MS–NH2) nanosphere, and superparamagnetic Fe3O4 nanoparticles scattered inside the silica sphere, was prepared by using a facile procedure. The composite combined the catalytic properties of amino groups and Pd nanoparticles with superparamagnetic properties of magnetite into a single platform. This integrated nanosystem acted as an efficient magnetically recyclable noble metal-base multifunctional nanocatalyst and showed excellent catalytic activity, selectivity and stability for the direct synthesis of α-alkylated nitriles under mild conditions through facile one-pot multistep cascade reaction sequences.
