Novel substituted pyrazolo[1,5-a]pyrimidine-2-sulfonamide compounds, such as 3-cyano-5,7-dimethyl-N-2,6-dichlorophenylpyrazolo[1,5-a]pyrimidine-2-su lfonamide, were prepared by the condensation of novel substituted 2-benzylthiopyrazolo[1,5-a]pyrimidine compounds, such as 2-benzylthio-5,7-dimethylpyrazolo[1,5-a]pyrimidine, and substituted anilines and found to be useful as herbicides.
新型取代的吡唑并[1,5-a]嘧啶-2-磺酰胺化合物,例如3-氰基-5,7-二甲基-N-2,6-二氯苯基吡唑并[1,5-a]嘧啶-2-磺酰胺,通过新型取代的2-苄基硫代吡唑并[1,5-a]嘧啶化合物,例如2-苄基硫代-5,7-二甲基吡唑并[1,5-a]嘧啶和取代苯胺的缩合反应制备,发现其可用作除草剂。
