Abstract

Kinetics and mechanism of oxidation of Mandelic acid by N-Bromo-iso-nicotinamide have been investigated in an aqueous acetic acid medium, in the presence of perchloric acid as the source of [H+]. Mercuric acetate, a bromide ion scavenger, has been studied in the 350 C range. The rate is first-order concerning [NBIN] and fractional or zero order of the reaction concerning [substrate]. The influences of Hg(OAc)2, HClO4 ionic strength, and bromide ion rate was found to be insignificant. An intermediate complex formed an oxidant with the substrate. In a slow and rate-determining step complex to give the product. problems to be solved in the establishment of the rate of reaction and different factors such as concentrations of oxidant, reactants, reaction medium, etc., and interpretation of the provided further support to the proposed mechanism and Activation parameters have been calculated.
