苯硫甲基磺酰胺(1)与4,6-二氯-2-三嗪异氰酸酯以碳酸钾为触媒在甲苯中加热回流制得N-4,6-二氯-2-三嗪基苯硫甲基磺酰脲(2),后者进一步与甲醇钠作用得N-4,6-二甲氧基-2-三嗪基苯硫甲基磺酰脲(3)。化合物3d经测试,具有一定的除草活性。

Eight novel triazinyl phenylthiomethanesulfonyl ureas (2, 3) were prepared by reacting phenylthiomethanesulfonamides (1) with 4, 6- dichloro-2-triazinyl isocyanate using potassium carbonate as catalyst, and then treated further with sodium methoxide in methanol. At 1000g (a.i.)/ha preemergence and 500g (a.i.)/ha postemergence the compound 3d showed 100% and 60% control of Raphanus S L respectively.
