2,4-Diamino-1-thia-3-azabutadienes 1 were studied. Methylation occured at sulfur and acylation at nitrogen hound to the 2 position. Alkylation by α-bromoketones gave rise to 2-amino-5-acylthiazoles. Upon treatment with acrylic dienophiles compounds 1 reac

The synthesis of dihydropyrimidines, dihydropyrimidinones and thiadiazine-1,1-dioxides starting from neutral or cationic 2-methylthio-1,3- diazadienes is described. Addition of H2S followed by loss of methanethiol led to the corresponding thiocarbonyl compounds.
