| Abstract: | The kinetics and mechanism of oxidation of some heterocyclic aldehydes viz. furan-2-aldehyde, pyrrole-2-aldehyde and thiophene-2-aldehyde by acid bromate in H2SO4 - HOAc medium have been studied. The reaction is first order each in [BrO3 -] and [substrate] and second order in [H+]. The products of oxidation are the corresponding carboxylic acids. From the study of effect of hetero atom of the molecule on rate, HBrO3 and protonated heteroaldehyde have been established as the reactive species. The order of reactivity is found to be furan-2-aldehyde > pyrrole-2- aldehyde> thiophene-2-aldehyde. A suitable mechanism has been proposed and discussed. |
