Three pyrimidine derivatives (8a-c), differing from isouramil and divicine at C2, have been synthesized and their autoxidation rates measured spectrophotometrically. The autoxidation rates of all five pyrimidines (8a-c, isouramil and divicine) were correl

The use of potassium persulfate in cold sodium hydroxide solution has been shown to give the pyrimidin-5-yl hydrogen sulfates in cases where the pyrimidine has at least two electron-releasing groups in the 2, 4 or 6 positions.However, the reaction has been unsuccessful in a number of cases.The pyrimidin-5-yl hydrogen sulfates are hydrolysed to the corresponding 5-hydroxypyrimidines by hydrochloric acid.
