Description
Summary:Cu super(II) immobilized on aminated ferrite nanoparticles by 2-aminoethyl dihydrogen phosphate (Fe sub(3)O sub(4)AEPH sub(2)-Cu super(II)) was prepared and characterized using FT-IR, TGA, TEM, EDX, VSM, XRD, CHN and ICP techniques. The easily prepared heterogeneous nanocatalyst demonstrated a significant catalytic performance for the transformation of aldoximes to nitriles that is far superior to previously reported methods. The reaction allows for the conversion of a wide variety of aldoximes including aromatic, aliphatic and heterocyclic aldoximes in good to excellent yields (50-98%). High efficiency, mild reaction conditions, easy work-up, operational simplicity, simple purification of products and safe handling of the catalyst are important advantages of this method. In addition, the environmentally benign heterogeneous nanocatalyst can be easily recovered from reaction mixtures using an external magnet and reused several times without any loss of activity. Cu super(II) immobilized on aminated ferrite nanoparticles by 2-aminoethyl dihydrogen phosphate (Fe sub(3)O sub(4)AEPH sub(2)-Cu super(II)), was prepared and characterized. The heterogeneous catalyst has been successfully applied in the transformation of aldoximes to nitriles. Efficient transformation, mild reaction conditions, easy product isolation and the potential reusability of the catalyst are attractive features.
