Abstract
Abstract Temperature dependences of the relative reactivity of substituted phenols RC 6 H 4 OH in the presence of potassium hydrogen carbonate and of potassium phenoxides RC 6 H 4 O− K+ toward 2, 4-dinitrophenyl benzoate in dimethylformamide were studied using the competitive reactions technique. Correlation analysis of the relative rate constants k R/k H and differences in the activation parameters (ΔΔH≠ and ΔΔS≠) of competitive reactions ...
