The title reactions are subjected to a kinetic analysis in ethanol-water, at 44 wt% ionic strength 0.2 (KCl). With a large excess of amine over the substrate, pseudo-first-25.0ะŠC, order rate coefficients are obtained, which are linearly dependent on the amine concen-(k ) obs tration. The nucleophili
