Utilisation des correlations de hammett a l'etude des equilibres tautomeres

Analytica Chimica Acta, 1972
The acidity constants for various substituted benzoic acids and anilinium cations have been measured potentiometrically in aqueous dimethylsulphoxide media at 20°. The values obtained (pKXS) are compared with the corresponding values for aqueous media (pKXE).

Correlation between the Hammett Acid Constants of Oxides and Their Activity in the Dealkylation of Cumene

Theoretical and Experimental Chemistry, 2003
On the basis of the TPR spectrum of cumene adsorbed on oxide catalysts, the temperature dependence of the maximum rate (Tm) of formation of benzene on the Hammett acidity of the samples has been found to be expressed by the equation H0 = 21.47 − 13.88·103/Tm.

The application of the Hammett equation to 13C N.M.R. spectroscopy: correlations in the β-nitrostyrenes

Australian Journal of Chemistry, 1976
A series of 33 ß-nitrostyrenes has been prepared and their 13C N.M.R. spectra have been determined in dimethyl sulphoxide and in deuterochloroform (where soluble). Hammett correlations between substituent and the chemical shift of both the para ring carbons and the a-carbon of the ethenyl group have been shown to be only approximate.
