Description / Table of Contents:
The NMR spectra of fifteen para-substituted acetanilides, XC6H4·NH·CO·CH3 (X = NH·CO·Me; NH2; CO·OEt; COOH; Cl; OEt; F; H; OMe; CH3; NO2; C6H5; —N=N—C6H5; Me3Si), have been recorded. δCH3 and δNH are linearly related to Hammett's σp constant. The coupling J (o-H—H) between aromatic protons is mainly dependent on σR0. J(13C—H), in methyl group is approximatively constant in the series.
Notes:
Les spectres de RMN de quinze acétanilides para-substitués XC6H4·NH·CO·CH3 (X = NH·CO·ME; NH2; CO·OEt; COOH; Cl; OEt; F; H; OMe; CH3; NO2; C6H5;—N=N—C6H5; Me3Si) ont été étudiés. Il y a une relation linéaire entre δCH3 et δNH et les constantes σP de Hammett. Le couplage J(o-H—H) entre les protons aromatiques est relié plutôt à σR0. La constante J (13C—H) dans le groupe CH3, est indépendante de X.
