1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
Quantitative evaluations of the percentages of rotational isomers in 1-vinyl-l, Z 4-triazoles were obtained. The population of the s.cis(N(2)) form in 1-vinyl-l,2,4-triazole is greater by a factor of two than in the s-trans form. ## Quantitative evaluations of the percentages of the rotational isom
