Oxidation of Styrene by nano magnetically coordination compound from Fe3O4 and Cu(II) complex

The oxidation of organic compounds using Schiff base complexes has been a field of academic and industrial interest to analyze the catalytic activity of various metal complexes [1–2]. In this project, a new nano-magnetically-compound was synthesized from Cu(II) complex and nano-Fe3O4 by covalently bond and characterized by generaltechniques such as: FTIR, UVD, XRD, SEM and EDX. A Cu complex is covalently anchored to Fe3O4 nano-particle by formation of Imine bonds. On the other hand, a Cu-Schiff base complex immobilized on nano-Fe3O4 by a Dopamine as a bridge (Scheme.1).As a result, the homogenous complex is easily converted to the heterogeneousmagnetically compound. Then, catalytic property of this compound was studied on oxidation of Styrene by tert-butyl hydroperoxide (TBHP) as an oxidizing agent at room temperature. The results showed a solvent free, green, selective, high yield and effective oxidation. The main product is Benzaldehyde. Then, the catalytic properties enhanced by cooperation of Cu complex and Fe3O4.
