Peroxo Complexes and Their Oxygen Transfer Reactions

Abstract

The chemistry of the peroxo complexes of various transition metals has received considerable attention in recent· years mainly because they are sources of active oxygen atoms and can be used as stoichiometric as well as catalytic oxidants for organic and inorganic substrates; eg,, they can be successfully used for the oxidation of olefins, ketones, phosphines, arsines etc. We have successfully employed peroxo complexes to generate glycerine from allyl alcohol which is. indeed an industrial aspect of the project. The present thesis describes isolation and characterisation of different peroxo complexes of Zr (IV), Th (IV), Mo (VI), W .{ VI) and U {VI) . ions containing different bi-dentate, tri-dentate and quardri-dentate ligands. A few oxygen transfer reactions of the complexes towards olefins, ketones, triphenyl phosphine and tripheny] arsine have been investigated.-----
