Abstract
N-(Substituted-phenyl)-7-ethoxy-5-fluoromethyl-1,2,4-triazolo[1,5-a]pyrimid ine-2-sulfonamides are prepared from 2-benzylthio-5-fluoromethyl-1,2,4-triazolo[1,5-a]pyrimidines and found to be herbicidal. The compounds, illustrated by 7-ethoxy-5-fluoromethyl-(2,6-dichloro-3-methylphenyl)-1,2,4-triazolo[1,5-a ]pyrimidine-2-sulfonamide, are degradable in the soil and are selective to wheat.
