Ten new N-[3-(3,4-dimethyl-1H-pyrrole-2-yl)-5-mercapto-4-triazole]-substituted-aryl(oxy)amides were synthesized by the reaction of 5-(substituted-phenyl)-2-furoyl-chloride or (substituted phenoxy)- acetyl chloride with 3-(3,4-dimethyl-1H-pyrrole-2-yl)-4-amino-5-mercapto-triazole in acetonitrile. The structures of the target compounds were confirmed by ¹H NMR, IR spectra and elemental analysis. The preliminary biological tests show that most of the target compounds have herbicidal activities.

Key words: 1,3,4-triazole, synthesis, aryl(oxy)amide, herbicidal activity, 3,4-dimethyl-1H-pyrrole
