Abstract :

The simplified recovery, reusability and the potential for incorporation in continuous reactors and microreactors are unique properties in organic synthesis, thus the major area of research is recently shifted toward more environment friendly catalysts. In homogeneous systems it is complicated to recover the catalyst from the final reaction mixture; thus heterogeneous catalysts are used as supports. Heterogeneous catalysts have attracted a considerable attention in synthesis of organic compounds, because of their recovery by conventional filtration or centrifugation techniques. However, recovery and recycling of the heterogeneous catalysts are difficult because they require a tedious workup via filtration and the inevitable loss of solid in the recovery process. Magnetic nanoparticles have recently proposed as ideal supports because of their multifunctional physical and chemical properties such as easy preparation and functionalization, high chemical activity, long catalytic life, large surface area ratio, excellent thermal and chemical stability, low price, less toxicity, high dispersion and easy separation via external magnet. Sulfoxides, disulfides and sulfides are useful in the chemical industries and play a vital role in some medicines and biological processes. During the recent increasing interest in synthesis of these compounds, variety of catalysts has been received considerable attention. The present work describes the synthesis of a new cadmium complex immobilized on Fe3O4 nanostructure as efficient catalyst for oxidation reactions. Characterization of the prepared nanostructure was performed by SEM and XRD. Use of green medium, easy separation, excellent reusability of the nanocatalyst, and short reaction time are outstanding advantages of this method. Recent Publications 1.
