Abstract: 1H and 13C NMR spectra of ethyl benzenecarboximidates (Ⅰ) and ethyl N-(ethoxycarbonylmethyl) benzenecarboximidates (Ⅱ) were determined. The resonance lines of these compounds were assigned, and the empirical substituent increments of -C-OEt=NH and -C-OEt=NCH2 CO2 Et were obtained. It was found that therewere some linear relationships between chemical shifts and Hammett constants σ.

Key words: Imidate, NMR, Chemical shift, Substituent increment, Hammett constant
