The industrial herbicide 5-(1,3,3-trimethylureido)-N,N-dimethyl-1,3,4-thiadiazole-2-sulfonamide and other compounds of similar structure may be made by a novel procedure in which the first step is the oxidative chlorination of a 2-alkylamino-5-mercapto-1,3,4-thiadiazole to yield the corresponding sulfonyl chloride. The subject compound which possesses five methyl substituent groups is more effective as a herbicide than compounds which contain other alkyl substituents or a lesser number of methyl substituents.
工业除草剂5-(1,3,3-三甲基脲基)-N,N-二甲基-1,3,4-噻二唑-2-磺酰胺和其他类似结构的化合物可以通过一种新颖的方法制备,其中第一步是氧化氯化2-烷基氨基-5-巯基-1,3,4-噻二唑,生成相应的磺酰氯化物。具有五个甲基取代基的该主体化合物作为除草剂比含有其他烷基取代基或更少数量的甲基取代基的化合物更有效。
