Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonamides, e.g., 5,7-dimethyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulf onamide and their agriculturally acceptable salts are prepared. These compounds and compositions containing them are useful for the control of unwanted vegetation. Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonyl chlorides and substituted anilines and their use as intermediates are also described.
新型取代的 triazolo[1,5-a]pyrimidine-2-磺酰胺,例如,5,7-二甲基-N-(2,6-二氯苯基)-1,2,4-三唑[1,5-a]pyrimidine-2-磺酰胺及其农业上可接受的盐类被制备。这些化合物和含有它们的组合物对于控制不需要的植被是有用的。还描述了新型的取代 triazolo[1,5-a]pyrimidine-2-磺酰氯和取代苯胺及其作为中间体的使用。
