Abstract

1-Aryl-2-phenyl-4-thioalkyl-4-secondaryamino-1,3-diaza-1, 3-butadienes 8 yielded interesting pyrimidones 10, 22 and 7 with chloroketenes 2, 11 and 12 through their episulfonium intermediates, whereas 1-aryl-2-phenyl-(methylthio) -4-dimethylamino-1,3-diaza-1,3-butadienes 1 give different pyrimidones with different haloketenes (chloro, bromo and iodo).
