3-aryl-substituted 1,2,4-oxadiazoles to electron-deficient alkyne; phenyl propiolic acid affords a series of 1,2,3-triazole derivatives carrying 3-p-substitutedphenyl-1,2,4-oxadiazolyl methyl unit. The structures of all the cycloadducts were elucidated by IR, NMR (1H, 13C, 2D), MASS (low and high resolution) spectra, X-ray diffraction data, and physical characteristics (melting points and Rf values).
