A number of monosubstituted pyrazines, pyrimidines, and their N-oxides having the electron-donating amino groups were successfully iodinated.Depending on the reaction conditions, the 3-substituted pyrazine 1-oxides having a bulky dialkylamino group yielded the 6-iodo and 2,6-diiodopyrazine N-oxide derivatives together with some deoxygenated products.The mechanism with supportive evidence was presented to account for these chemical transformations.
