摘要：

2-Methylpyrimidine-4,6-dithiolhas been synthesized and has been converted into 2-methyl-6-methylthiopyrimidine-4-thiol, 4,6-bismethylthiopyrimidine and6,6'-dithiobis(2-methylpyrimidine-4- thiol).Oxidation of 4,6-bismethylthio-2-methylpyrimidine with 1, 2, 3 and 4 equiv. of m-chloroper-benzoic acid has been shown to result in the formation of the easily isolable methylsulfinyl(methylthio)-, bis(dimethylsulfinyl)-, methylsulfinyl(methylsulfonyl)- and bismethylsulfonyl-pyrimidine,respectively. Some further reactions of the above compounds are described andthe synthesis of some other pyrimidines having sulfur-containing substituentsis also described.
