Notes:
13C magnetic resonance spectra of nine quaternary ammonium salts of the general formula R1C1(O)C2H=C3HNR34Cl (where R1, R4 = alkyl) were obtained and compared with those of the parent amino compounds. The chemical shift differences between these two classes of compounds are qualitatively accounted for by π-electron density changes. Steric effects and hyperconjugation of the alkyl substituents are also discussed.
