Pt (II) Schiff Base Complex Catalyzed Oxidation of Internal and Terminal Alkenes

Abstract

Pt (II) complexes of Schiff base ligands were found highly efficient towards the catalytic oxidation of internal alkenes and terminal alkenes in dimethylformamide (DMF) solvent under normal pressure of molecular oxygen. In some catalytic reactions, H₂O₂ was also used as co-oxidant. No diminished catalytic activity was observed even after six to eight repeated catalytic runs. Effect of temperature and extra ligand etc. on the rate of oxidation, nature and percentage yield of products was also investigated. On the basis of kinetics and other experimental observations, a reaction mechanism has also been proposed.
