Possible examples for such processes are proton shifts (keto-enol tautomerism), addition reactions, eliminations after protonation of the leaving group (HO−/DO−), or hydrogen atom (H·) abstraction reactions, which would all show a kinetic isotope effect. In particular the last alternative ...

Meanwhile, the rate constants in PEA solvent are less significant, being 4.02 × 101 M-1 s-1 and 8.16 × 102 M-1 s-1 for Cur-I and Cur-III, respectively. Due to the dominant molar fraction of the keto-enol form compared to the diketone, the reaction rates are primarily attributed ...
