Various monosubstitudes pyrimidines and methylpyrimidines were N-oxidized with a number of different peracids.In general, they are more susceptible to side reactions accompanying N-oxidation (i.e., decomposition, annular carbon oxidation, ring opening) than other ?-deficient diazine and triazine analogs.Unsymmetrical pyrimidines, which can potentially yield two isomeric products, were N-oxidized preferentially at the site para to strong electron-donating substituents.Weaker ringactivating groups, such as methyl, are mainly ortho directing and only aid in the N-oxidation of pyrimidine nuclei having ortho/para-directing substituents.
