    摘要: Substituted N-aryl[1,2,4]triazolo[1,5-a]-pyrazine-2-sulfonamide compounds, such as 5-bromo-N-(2,6-dichlorophenyl)-8-methoxy[1,2,4]triazolo[1,5-a]-pyrazine-2-sulfonamide, were prepared by condensation of a substituted 2-chlorosulfonyl[1,2,4]triazolo[1,5-a]pyrazine compound, such as 5-bromo-2-chlorosulfonyl-8-methoxy[1,2,4]triazolo[1,5-a]pyrazine with a substituted arylamine compound, such as 2,6-dichloroaniline, and found to possess herbicidal utility.
