چکیده    Mechanistic study on meso-tetraphenylporphyrin iron(iii) chloride (tpp) catalysed oxidation of indole-3-acetic acid by peroxomonosulphate (oxone) in aqueous acetonitrile medium has been carried out. the reaction follows a first order with respect to both substrate and oxidant. the order with respect to catalyst was found to be fractional. the order of reaction with respect to catalyst varies with a concentration of catalyst. increase in percentage of acetonitrile decreased the rate. the reaction fails to initiate polymerization,and a radical mechanism is ruled out. activation and thermodynamic parameters have been computed. a suitable kinetic scheme based on these observations is proposed. significant catalytic activity is observed for the reaction system in the presence of tpp. © 2013 durairaj kungumathilagam and kulanthaivel karunakaran.
