✦ Synopsis

15 N NMR data of a series of 3-alkyl[aryl] substituted 5-trichloromethyl-1,2-dimethyl-1H-pyrazolium chlorides (where the 3-substituents are H, Me, Et, n-Pr, n-Bu, n-Pe, n-Hex, (CH 2 ) 5 CO 2 Et, CH 2 Br, Ph and 4-Br-C 6 H 4 ), are reported. The 15 N substituent chemical shifts (SCS) parameters are determined and these data are compared with the 13 C SCS values and data obtained by MO calculations.

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.
