Abstract

Abstract The title reactions are subjected to a kinetic analysis in 44 wt% ethanol-water, at 25.0 C, ionic strength 0.2 (KCl). With a large excess of amine over the substrate, pseudo-first- order rate coefficients (k obs) are obtained, which are linearly dependent on the amine concentration. The nucleophilic rate constants (k N) are determined from plots of k obs vs. amine concentration. The Brönsted-type plot obtained with the k N values is linear, with ...
