A series of new 2-(5-phenoxymethyl-4-phenyl-1,2,4-triazol-3-ylsulfanyl)-N-aryl-acetamides were synthesized by the reaction of S-alkylation from N-phenyl-2-chloroacetamide reacting with some triazole derivatives in aqueous media without catalysis. The structures of all synthesized compounds were confirmed by elemental analysis, IR and 1H NMR spectra. The crystal structure of 5n was determined by X-ray diffraction analysis. The supramolecular tri-dimensional netlike structure was formed by intermolecular hy-drogen bonding. The preliminary biological tests showed that some of the title compounds remarkably en-hanced the root elongation, and all compounds inhibited the plant stem in the whole range of concentrations.
