independent measurement of the kineticisotope effect, allowed the kinetic effect of the alkyl environment on the relative proton transfer rates to be determined. The primary and secondary isotopeeffects are also estimated from the enolate ion product ratios. By examining the magnitude of the kinetic alkyl effect, the primaryisotope effect, and the secondary isotope effect, we learn about the transition
