| Abstract | The kinetics of Tl(III) perchlorate oxidation of some active methylene compounds viz. ethyl acetoacetate and diethyl malonate has been studied in acetic acid-water mixture in the presence of perchloric acid. <br> <br>The reactions show first order in oxidant while the order in both the esters vary from one to zero. The order with respect to hydrogen ion is one for ethyl acetoacetate oxidation while one to zero in malonic ester oxidation. Added Cl- inhibits the rate of reactions. The effect of variation of ionic strength of the medium has been investigated. The stoichiometry of the title reaction is found to be 1:2. The activation parameters have been evaluated. Based on these finding a probable mechanism has been proposed. |
