'Effect of axial ligands in the structure and reactivity of oxomanganese (IV)-salen complexes and its Biomimitic oxidation towards organic sulfides: ' Mechanistic aspects of oxygenation (ET/OAT) reactions catalyzed by transition metal complexes are fundamental importance in biological field.1,2 The systematic structural investigation is not well characterized, however the steric, electronic factors that control the reactivity and selectivity of the oxygenation of substrates catalyzed by metal complexes is of much interest.3-9 The Mn-peroxo/oxo species bearing non-heme ligands have been spectroscopically characterized and their reactivities have been well demonstrated. Spectroscopic data including electronic absorption (UV-vis), resonance Raman, electronic paramagnetic resonance (EPR) and x-ray absorption spectroscopy/extended x-ray absorption spectroscopy (XAS/EXAFS) of manganese-peroxo/oxo species were reported.5-8 Based on the literature we decided to investigate the synthesis and characterization of Manganese-salen complexes bearing anionic axial ligands (electron withdrawing groups). The aforesaid complexes will be characterized by UV-vis, IR, NMR, ESI-MS spectroscopic and cyclic voltammetric method. In this work we will use hydrogen peroxide/iodosyl benzene as the oxidizing agent. Finally we will check the catalytic ability of these oxidants by kinetically oxidizing the biologically important sulfides by spectrophometric method in this present study and suitable mechanism will be proposed.
