Popis: The reactions of a series of secondary alicyclic amines with the title substrates (DNPDTC and TNPDTC) are subject to a kinetic study in water at 25.0 o C, ionic strength 0.2 M (KCl). The reactions are first order in both the amine and the substrate. The Bronsted-type plots obtained are nonlinear and are explained by a stepwise mechanism through a zwitterionictetrahedral intermediate (T ± ), although a concerted process is not rigorously excluded for the reactions of the less basic amines with TNPDTC
