ABSTRACT:
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.
