In view of spectracular importance of Schiff bases (azomethines) lies in their formation of coordination compounds readily with metals. This is due to the presence of lone pair of electrons on the nitrogen atom and of the general electron donating character of the double bond. They also form five or six membered stable cheletes with metals if a functional group with a replaceable hydrogen atom, preferably a hydroxyl group is present near enought to the C-N group. Besides the ability to form complexes with metals, Schiff bases have innumerable applications in many fields namely, pharmacy,...

Nano catalysis can help design catalysts with excellent activity, greater selectivity, and high stability. These characteristics can easily be achieved by tailoring the size, shape, morphology, composition, electronic structure, and thermal and chemical stability of the particular nanomaterial. Nano catalysts enjoy several advantages over conventional catalyst systems; however, isolation and recovery of these tiny nano catalysts from the reaction mixture is not easy. Conventional techniques (such as filtration) are not efficient because of the nano size of the catalyst particles. This...
