The oxidative coupling and aromatization of 3,4-dihydropyrimidin-2-thiones to produce 1,2-di(pyrimidin-2-yl)- disulfides by using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as oxidant at room temperature under an air atmosphere are reported. Compared with the reported procedures, this method has obvious advantages at mild reaction conditions including lower reaction temperature and shorter reaction time with higher yields of products.

Key words: 3,4-dihydropyrimidin-2-thiones, 1,2-di(pyrimidin-2-yl) disulfides, DDQ, oxidative coupling
