A mixture of 4-(2-acetylaminobenzoyl)-5-phenyl(p-cumenyl)-1-/sup 15/N,2,3- and 4-(2-acetylaminobenzoyl)-5-phenyl(p-cumenyl)-1,2,3-/sup 15/N-triazoles was obtained from 1-acetyl-2-arylmethylene-3-indolinones and Na/sup 15/N/sub 3/ with the label at the terminal position. The tautomeric composition of the mixture, which corresponds to a state of equilibrium between the 2H and 3H forms of the triazole ring, was established by /sup 1/H (at low temperatures) and /sup 15/N NMR spectroscopy. The 4-(2-acetylaminobenzoyl)-5-aryl-1,2,3-triazoles are acylated at the sterically less hindered position 2 of the triazole ring.
