Abstract

Polymer-anchored transition metal complexes were synthesized by supporting cobalt (II), iron (III) and copper (II) on anion exchange resin (polystyrene) through the ligand thiosemicarbazone. The resulting catalysts were characterised by elemental analysis, SEM, IR spectroscopy, ESR and thermal studies. The catalysts were found to be active for oxidation of some alcoholic substrates under ambient conditions of temperature and pressure. The influence of solvent polarity on the rate of reaction was studied. Kinetic studies were done by varying the parameters like concentration of catalyst and substrate. The catalysts were found to have recycling efficiency for 5-6 cycles.
