Determination and Structural Correlation of Pk A Values of P-Substituted Trans-β-Aroylacrylic Acids

Abstract

For a series of 10 p-substituted trans-β-aroylacrylic acids, pK_a values were determined spectrophotometrically in water at 25°C and at ionic strength 0.1 M (NaCl). The thermodynamic pK_a values were correlated with Hammett σ_p constants.
