    4-(N,N-Dialkylthiocarbamoylthio)-5-nitropyrimidines as new potential nitric oxide donors

    On heating at pH 6.86, 4-(N,N-dialkylthiocarbamoylthio)-5-nitropyrimidines are transformed into dithiolopyrimidines, which are either oxidized to bis(4-dialkylthiocarbamoylpyrimidin-5-yl) disulfides or converted ...
