Copper( ii ) complex-decorated ZrFe ₂ O ₄ nanoparticles as a recyclable magnetic nanocatalyst for synthesis of N-containing heterocycles

)-one derivatives, through click and cyclization reactions, respectively. The reactions were conducted under mild conditions, affording high yields in short reaction times. Furthermore, the catalyst demonstrated excellent stability and reusability, with minimal copper leaching observed across multiple catalytic cycles.
