    • S-TRIAZINE DERIVATIVES ARE OBTAINED BY REACTING A COMPOUND OF THE FORMULA WHEREIN R1 and R2, which may be the same or different, each represents hydrogen or an optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical and X represents oxygen or sulphur WITH A SUBSTANTIALLY EQUIMOLAR QUANTITY OF N-chlorocarbonyl isocyanate at a temperature of from about -100* C. to about +200* C., optionally in the presence of an inert organic solvent. The novel compounds that can be obtained by the process according to the invention have the general formula

      WHEREIN X represents oxygen or sulphur and R1 and R2, which may be the same or different when X represents sulphur but which must be different when X represents oxygen, each represents hydrogen or an optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical. They can be used as herbicides.
    • 通过反应式I化合物可以得到S-TRIAZINE衍生物,其中R 1和R 2可以相同或不同,各自表示氢或任选取代的脂族,脂环族,芳脂族,芳族或杂环基,X表示氧或硫 在约-100℃至约+200℃的温度下,任选在惰性有机溶剂存在下,得到N-氯代羰基异氰酸酯的大体平均数。
