Abstract

Abstract The kinetics of the reactions of 4-methylphenyl, phenyl, and 4-chlorophenyl 2, 4, 6- trinitrophenyl carbonates (1, 2, and 3, respectively) with a series of anilines and secondary alicyclic (SA) amines has been carried out spectrophotometrically in 44 wt% ethanol–water, at 25.0 C, ionic strength 0.2 M. The Brønsted plots (statistically corrected) for the reactions of carbonates 1–3 with anilines and SA amines were linear with slopes (β N) in the range of ...
