Novel pyrimidine derivatives were prepared from the reaction of 2-substituted 1,3-bis(dimethylamino)-trimethinium salts with thiourea or guanidine in the presence of ethyl-diisopropylamine in ethanol at reflux, and also some 5-substituted pyrimidine-2-thiols has been used for the synthesis of novel disulfane compounds. Infrared, 1H NMR, 13C NMR, and mass spectral data confirm the molecular structures of the newly synthesized compounds. The ultraviolet spectral behavior of these compounds was examined in DMSO and the ?max of these compounds was studied.
