Copper(II) Schiff Base Complex Immobilized on Core-shell Fe3O4@SiO2 as a Magnetically Reusable and Highly Efficient Nanocatalyst for the Green Synthesis of 2-Amino-4H-chromene derivatives

Fe3O4 based a new Cu(II) Schiff-base complex has been prepared by treating 1,3-Phenylenediamine with Salicylaldehyde in ethanol 1-4. This catalyst has been characterized by TEM, SEM, XRD, FT-IR, TGA, XPS, VSM, ICP, EDX and successfully applied as a magnetically recyclable heterogeneous catalyst for the efficient one-pot, three-component synthesis of 2-Amino-4H-chromene derivatives. The catalyst can be recovered by magnetic separation and recycled several times without significant loss of catalytic activity
