Abstract:

1,2,3-Triazole compounds show a wide range of biological activities. In order to find new compounds with bactericidal activity, a series of 2-substituted-4-aryl-2H-1,2,3-triazoles was synthesized from benzaldehyde or substituted benzaldehyde, nitromethane and sodium azide in 51% to 91% yields. The structures of these compounds were characterized by nuclear magnetic resonance spectroscopy(NMR), mass spectra and elemental analyses. Most of these compounds show the preliminary antibacterial activity against Gibberella zeae and Phytophythora capsici in vitro, in 25 mg/L concentration. Among them, compound 3a shows 80.4% activity of against Gibberella zeae, compound 3b shows 78.2% activity of against Botrytis cinerea, compounds 3a and 3h show 70.3%, 75.9% activities of against Sclerotonia sclerotiorum, respectively.

Key words: triazole, structure characterization, fungicidal activity
