The kinetic and mechanistic aspects of cerium(III)- catalyzed oxidation of 4-oxo acids by bromate (uncon taminated with bromine) in an acid medium have been studied. The reaction exhibited first-order each in [bromate] and [acid], fractional order each in [oxo acid] and [cerium(III)], and also showed solvent isotope effect of 0.55 (k(H2O)/ k (D2O)). The reaction did not induce polymerization and the induction period was not observed The influence of ionic strength on the rate was negligible, while increase in reaction rate was found by lowering the dielec. constant of the me dium. The reaction rate was affected by the presence of substituents in the reaction center. Increase in the reaction rate by electron releasing substituents and decrease in the rate by the presence of electron-with drawing substituents were observed The Hammett plots were characterized by smooth curvature; how ever, linearity was observed using exalted ¦Ò values. A neg. value for the reaction constant was observed The isokinetic relationship was evaluated from the Arrhenius and Hammett plots. The formation of a ternary complex between oxidant, substrate and catalyst has been proposed in the mechanism. Based on the proposed mechanism, the rate law has been deri ved. The formation of a ¦Ð-complex between Ce(III) and -ene of the enol form of oxo acid has been pro posed. This reaction finds application in the synthesis of substituted benzoic acids and involves the pheno mena of intramol. catalysis and neighboring group participation.
