摘要:

13C NMR proton noise and single frequency off-resonance decoupled spectra were obtained for a series of 4-substitutedN-[(dimethylamino)methyl]-benzamides. The various carbon resonances have been assigned on the basis of the chemical shift theory, multiplicities observed in partially coupled spectra, signal intensities, additivity rules, and by comparison with structurally related compounds. When the substituent parameters of Swain and Lupton were plotted against the δC˭O′ a reasonable correlation (r = 0.94) was found.
