Kinetic solvent isotope effect [k(H3O+)/k(D3O+)<1] and deuterium incorporation (ca. 100%) during acidic hydrolysis of keten selenoacetals establish that these reactions proceed through a pre-equilibrium carbonprotonation step.
酮型硒缩醛的酸性水解过程中的动力学溶剂同位素效应[ k(H 3 O +)/ k(D 3 O +)<1]和氘的掺入(约100%)确定了这些反应通过平衡前的碳质子化进行步。
