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-25.0ะC, order rate coefficients are obtained, which are linearly dependent on the amine concen-(k ) obs tration. The nucleophili
## Abstract We report a kinetic study on the reactions of secondary alicyclic amines toward 4โnitrophenyl, 2,4โdinitrophenyl, and 2,4,6โtrinitrophenyl acetates (**1, 2**, and **3**) in ethanol/water mixtures of different compositions. It is found that (i) the intermediate in the reaction of **1** i
