Abstract
Abstract Twenty-two 2,4-dinitroanilines were synthesised and their p K a values were determined. The 2,4-dinitroanilines and their protonated forms were studied by 15 N NMR spectroscopy. The relations between the 15 N NMR chemical shifts and the p K a values of the 2,4-dinitroanilines and their salts were found to be linear. The deprotonation reaction of N -methyl-2,4-dinitroanilines and N -methyl-2,4,6-trinitroaniline by MTBD was successful only for the latter and yielded protonated MTBD molecule and the anion in which the electrons are strongly delocalised. The kinetic parameters of the 2,4-dinitroanilines in reactions with hydroxide ions in mixed solvent DMSO:water (95:5, v/v) were determinated and discussed.
