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.

Abstract
^1^H and ^13^C NMR studies were carried out on the substituted dihydronaphthalene compounds 1,2‐dihydro‐8‐isopropyl‐6,7‐dimethoxy‐2‐methylnaphthalene, 3‐bromo‐1, 2‐dihydro‐8‐isopropyl‐6, 7‐dimethoxy‐2‐methylnaphthalene, 3, 4‐dihydro‐5‐isopropyl‐6, 7‐dimethoxy‐3‐methyl‐1(2__H__)‐naphthalenone, 1, 2‐dihydro‐6, 7‐dimethoxy‐2, 8‐dimethylnaphthalene, 3‐bromo‐1, 2‐dihydro‐6, 7‐dimethoxy‐2, 8‐dimethylnaphthalene and 3, 4‐dihydro‐6, 7‐dimethoxy‐3, 5‐dimethyl‐1(2__H__)‐naphthalenone. Complete assignments of the proton and carbon spectra were made using one‐ and two‐dimensional NMR techniques including APT, COSY, NOESY and ^1^H‐^13^C HETCOR spectroscopy.
