Chemistry of 4-dicyanomethylene-1,2,6-thiadiazines
Journal of the Chemical Society, Perkin Transactions 1, 2000 The chlorine atoms in 3,5-dichloro-4-dicyanomethylene-1,2,6-thiadiazine 1 are readily displaced by thiophenols in the presence of Hunig’s base, the first at −78 °C and the second at 20 °C to give the orange mono- and bis-arylthio derivatives in high yield (Table 1).

Cyclisation chemistry of 4H-1,2,6-thiadiazines
Journal of the Chemical Society, Perkin Transactions 1, 2000 3,5-Dichloro-4H-1,2,6-thiadiazin-4-one 1 condenses rapidly at room temperature with 1,2-diaminobenzene, 2-aminothiophenol and sodium 2-aminophenoxide to give, respectively, the purple thiadiazinoquinoxaline 4a, red thiadiazinobenzothiazine 4b and orange thiadiazinobenzoxazine 4c in almost quantitative yield.
