In the kinetics of the alkaline hydrolysis of the 4-nitrophenyl esters of arylimidic acids R1C6H4C(OC6H4NO2-4)=NC6H4R2 in a water-dioxane mixture (1:1 by volume) with a constant ionic strength first order is observed in each of the reagents.The reaction rate depends little on the nature of the electrolyte (NaCl, NaClO4, LiClO4) and decreases with increase in the concentration of the salt in the solution.The ρ constants for the bimolecular process ρR1 = 2.0 0.1 and ρR2 = 2.4 0.2 agree with an addition-elimination mechanism with the formation of a tetrahedral intermediate product in the rate-determining stage.
