Non-limiting solvolysis of a 2-propyl sulphonate in trifluoroacetic acid. A redetermination of deuterium kinetic isotope effects
Abstract
Contrary to an earlier report, the α-deuterium isotope effect (kH/kD) for the trifluoroacetolysis of a 2-propyl arenesulphonate is smaller than 1.22 at 25 °C, suggesting that the reaction does not proceed via the limiting SN1 mechanism.
