The kinetics of the oxidation of the malic and by N-bromoanisamide in HC1O4 and in the presence of Hg(OAc)2 have been studied. The reactions exhibit a first order rate dependence with respect to the oxidant and substrate. The reactions are acid catalyzed and retarded by the addition of anisamide, a by product of reaction. The rate of oxidation decreases with decrease in dielectric constant of the medium. The effect of temperature on the reaction has been investigated in the temperature range 313-328 K. The stoichiometric studies revealed 1:1 mole ratio. Various thermodynamic parameters have been computed and a possible operative mechanism is proposed.
