Cu(II) Anchored on Modified Magnetic Nanoparticles: As a Green and Efficient Recyclable Nano Catalyst for One Pot Synthesis of 12-Aryl-8,9,10,12tetrahydrobenzo[a]xanthene-11-oneʺ

Cu(II) immobilized on Fe3O4@APTMS-DFX nanoparticles as a magnetically recyclable heterogeneous catalyst was synthesized and characterized by various techniques such as FT-IR, TGA, Sem- EDX, VSM, ICP, and XRD. The catalyst was demonstrated a superior catalytic activity towards the green one-pot synthesis of 12-aryl-8,9,10,12 tetrahydrobenzo[a]xanthene-11-one via the three-component reactions among of aromatic aldehyde, 2-naphthol and dimedone...
