Equilibrium CH-acidities of dimethyl 2-dimethoxyphosphoryl malonate and its thiophosphoryl analog

The pK_a values of dimethyl 2-dimethoxyphosphoryl malonate and of its thiophosphoryl analog have been measured by transmetallation using the inclusion complex of Li⁺ with [2.1.1]-cryptand as the metallation agent.Translated fromIzvestiya Akademii Nauk.
