In this work, a surface-modified magnetic solid support with the Cu (II) complex tags was prepared. The structure of newly prepared nanostructure was characterized by FT-IR, XRD, TGA/DTG, VSM, FE-SEM, EDS, and ICP/OES techniques. The catalytic activity of prepared hybrid nanomaterial was evaluated in the synthesis of tetrahydrobenzo[b]pyran and pyrano[2,3-d]pyrimidinone derivatives. Some advantages of this method are high yields, short reaction times, green solvent and conditions, easy workup procedure, negligible copper leaching, reusability without a significant diminish in catalytic efficiency and simple separation of nanocatalyst by using an external magnet alongside the environmental compatibility and sustainability
