Alkoxy substituted 1,2,4-triazolo[1,5-c]-pyrimidine-2-sulfonamides are prepared from alkoxy substituted 1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonyl halides by condensation with substituted N-trialkylsilylanilines and by other methods. N-(2,6-dichloro-3-methylphenyl)-5,7-dimethoxy-1,2,4-triazolo[1,5-c]pyrimid ine-2-sulfonamide is typical. The compounds are general and selective pre- and postemergence herbicides.
烷氧基取代的1,2,4-三唑并[1,5-c]-嘧啶-2-磺酰胺是通过烷氧基取代的1,2,4-三唑并[1,5-c]嘧啶-2-磺酰卤化物与取代的N-三烷基硅基苯胺以及其他方法进行缩合制备的。N-(2,6-二氯-3-甲基苯基)-5,7-二甲氧基-1,2,4-三唑并[1,5-c]嘧啶-2-磺酰胺是典型的化合物。这些化合物是通用的和选择性的前后除草剂。
