Abstract

The reaction of 6-oxo-, thioxo-2,3-dimethylthieno[2,3-d]pyrimidin-4-ones with electrophilic agents was studied. It was shown that during nitration these compounds undergo electrophilic unco-substitution forming 3-nitro- and 2-nitro-6-oxo- and 2,3-dinitro-6-thioxothieno[2,3-d]pyrimidin-4-ones, respectively; the reaction of these compounds with bromine proceeds in other directions.
