Zakrzewska, Anna published the artcile13C-NMR based evaluation of the electronic and steric interactions in aromatic amines, Safety of 2,6-Diisopropyl-N,N-dimethylaniline, the publication is International Journal of Molecular Sciences (2005), 6(1-2), 52-62, database is CAplus.
Chem. shifts of the para carbon atoms, ¦Ä(13C-4), in a series of aromatic amines were used to calculate the ¦Òp, ¦ÒR and ¦ÒOR substituent constants for different amino groups. 1-Pyrrolidino, N-N-di-n-butylamino and N,N-diethylamino groups were found to be the most strong electron-donors. Ortho-Substitution decreases the donor properties of the amino group. The amino groups in 2,6-di-i-propylaniline and N,N-2,6-tetramethylaniline have very weak electron-donor properties. The nitrogen atom in benzoquinuclidine and N,N-dimethyl-2,6-di-i-propylaniline have an electron-acceptor character. The calculated substituent constants of the amino groups studied are consistent with the spectral and reactivity data available in literature. Values of ¦Ä(15N) cannot be used as a direct measure of electronic effects of the N atom in anilines.
