Polymer Supported Schiff Base Iron Complex for Epoxidation of Trans-stilbene

N. Nath, H. C. Pradhan, T. Maharana, and A. K. Sutar
Abstract—In the present investigation, the novel recyclable polystyrene anchored iron complex supported by –ONN Schiff base is synthesized. This polymer anchored iron complex is prepared by the reactions of metal solution with one molar equivalent of polystrene supported Schiff-base ligands in methanol under nitrogen atmosphere. In contrast with other polymer-supported catalysts, the greatest advantage of this catalyst system was that the cost of the catalyst was remarkably low and recycled up to six times, due to the easily accessible materials and the simple synthetic route. The higher efficiency of complexation of metal ions on the polymer anchored Schiff base than unsupported analogue was another advantages of this catalyst system. The structural study reveal that iron(III) complex is octahedral in geometry.The catalytic activities of polystyrene supported iron complex toward the epoxidation of trans-Stilbene is investigated. Experimental results indicate that the reactivity of iron complex is dramatically affected by the polymer support and the rate of trans-Stilbene conversion was 4.27 × 10-7 moledm-3s-1 and obeys first order kinetics. The efficiency of supported catalysts remained almost constant upto six recycles.
