Reactions in strongly basic solutions. Part II. Correlations of the rates of alkaline hydrolysis of 1-substituted 2- and 4-nitrobenzenes and 4-substituted 1-methoxy-2-nitrobenzenes in aqueous dimethyl sulphoxide with an acidity function

Abstract

The rate coefficients for the alkaline hydrolysis of a series of 1-substituted 2- and 4-nitrobenzenes, and 4-substituted 1-methoxy-2-nitrobenzenes in aqueous dimethyl sulphoxide have been measured at 30·0°. These rates have been correlated with an acidity function of the medium. The slopes of the linear relations obtained are discussed in relation to the mechanism of the reaction and reactivity of the substrate. The reaction constant, ρ, for the hydrolysis of the 4-substituted 1-methoxy-2-nitrobenzenes has been evaluated and the results are discussed.
