A comparative kinetic study was made to determine whether the proposed deiodination mechanism2 may be extended to include deiodination of N, N-dimethyl-p-iodoaniline in acid medium. From the kinetic data obtained using classical iodometry, the rate constants and the activation energy of reaction are obtained. At 80⁰ C, the deiodination N, N-dimethyl-p-iodoaniline is faster by a factor of 5 than that of p-iodoaniline. This is explained in terms of chemical structure. In order to confirm the mechanism, the deuterium effect is measured and interpreted. The ratio KH20/kD20, is found to be 5.8. Infrared spectra of N, N-dimethyl-p-iodoaniline and N, N-dimethylaniline are given. The iodine- addition complexes of N, N-dimethyl-p-iodoaniline are described.
