Modern state of the art of catalysis science and research reveals that the introduction of novel nanotechnologies has enabled the generation of solid-supported heterogeneous nanoscale catalysts, which are effective tools for controlling chemical reactivity as well as conferring the synergistic benefits of facile recovery [1]. By collectively integrating the key advantages of homogeneous as well as heterogeneous catalysts, they offer great prospects of meeting the sustainability criteria consistent with the goals of green chemistry [2-3]. Mgnetic nanoparticles play the role of a bridge between heterogeneous and homogeneous catalysts and have emerged as promising catalysts due to their low-cost, efficient and reusable properties [4]. A magnetically recoverable heterogeneous Fe3O4@SiO2@BHA-Cu(II) nanocomposite was prepared by immobilizing a novel Cu(II) complex on the nanoparticles. The catalyst was characterized by FTIR, TGA, VSM, FESEM, XRD, ICP and EDX techniques. The catalytic activity of this nanocatalyst in the synthesis of polyhydroquinoline derivatives were investigated.
