Notes:
1H, 7Li, 13C, and 15N NMR spectra were observed for lithium salts of aniline derivatives in THF solutions. The delocalization of excees charge into the phenyl ring of the salts was confirmed from the 1H and 13C chemical shift data in comparison with those of the neutral molecules. Their 15N atoms were approximately 40 ppm less shielded comparison with those of the neutral molecules, and these are discussed in terms of hybridization change and electron densities at the nitrogen atoms. The one-bond 15N-1H coupling constants of the salts are approximately 55 Hz and are smaller than those of the neutral molecules.
