Differences between proton and hydride transfers are discussed. Theoretical reasons are given for expecting kH/kD isotope effects to increase markedly on introduction of electron- attracting substituents for proton transfers, but to be much less sensitive to substituents for hydride transfers. Therefore it is applied as a tool for distinguishing between proton and hydride transfers in the oxidation of 0.01-. 1 M 2-propanol by 0.001-0.008 This reaction is ...
