Cu(II) and magnetite nanoparticles decorated melamine-functionalized chitosan: A synergistic multifunctional catalyst for sustainable cascade oxidation of benzyl alcohols/Knoevenagel condensation.

ABSTRACT: The uniform decoration of Cu(II) species and magnetic nanoparticles on the melamine-functionalized chitosan afforded a new supramolecular biopolymeric nanocomposite (Cs-Pr-Me-Cu(II)-Fe₃O₄). The morphology, structure, and catalytic activity of the Cs-Pr-Me-Cu(II)-Fe₃O₄ nanocomposite have been systematically investigated. It was found that Cs-Pr-Me-Cu(II)-Fe₃O₄ nanocomposite can smoothly promote environmentally benign oxidation of different benzyl alcohol derivatives by tert-butyl hydroperoxide (TBHP) to their corresponding benzaldehydes and subsequent Knoevenagel condensation with malononitrile, as a multifunctional catalyst. Interestingly, Fe₃O₄ nanoparticles enhance the catalytic activity of Cu(II) spe
