## Abstract The^13^C NMR spectra of some 1‐(__N__,__N__‐diaroyl)amino‐1,2,3‐triazole derivatives are reported. The shifts of the methyl carbons attached to the triazole ring and those of C‐4 and C‐5 of the ring were used to distinguish between 4,5‐unsymmetrically substituted derivatives. The locati
The uC NMR spectra of three mesoionic 1,2,3-triazol-4-ylacetamides and two 1,2,3-triazol-4-ones were determined, and an evaluation of the shifts in relation to their mesoionic structure was made. A h e a r correlation between the I3C resonances and net charge densities, calculated by the CNDO/% meth
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.
