The research work deals with studies on the synthesis, characterization and catalytic activities of some transition metal complexes of the Schiff bases derived from 3-hydroxyquinoxaline-2-carboxaldehyde. Schiff bases which are considered as 'privileged ligands' have the ability to stabilize different metals in different oxidation states and thus regulate the performance of metals in a large variety of catalytic transformations. The catalytic activity of the Schiff base complexes is highly dependant on the environment about the metal center and their conformational flexibility. Therefore it is...
