    Selectivity in Oxidation Reactions of Methylthio Substituted Pyrimidines and Triazines - It was found during the oxidation of methylthio substituted pydmidines and 1,3,5-triazines that pyfimidinesulphones were obtained in better yield than triazinesulphones because the oxidation is influenced by the structure and substitution of heterocycles and it could have not been selectively stopped at this level. Depending on the pH and solvent, the methylsulphonyl and the formed methylsulphonium groups can rapidly take part in nucleophilic substitution reactions resulting in RO-triazine and -pyrimidine derivatives (R : = H, CH3). These reactions may be utilised in such processes where the methylthio substituted heterocycles are formed as by-products After their oxidation, the nucleophilic substitution leads to the desired clean products
