摘要

Alkoxy substituted 1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonamides are general and selective pre- and postemergence herbicides. These compounds are disclosed which 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.
