Abstract
1. The kinetics of the reversible addition of the methyl ester ofα-nitropropionic acid (MNP) to acetaldehyde in dimethyl sulfoxide (DMSO) under the action of the components of a triethylammonium buffer solution were studied. 2. The equilibrium constant of the addition of MNP to acetaldehyde in DMSO was determined, and the value previously obtained for this constant in water was refined. 3. The rate constant of the nucleophilic addition of the carbanion of nitropropionic ester to acetaldehyde, catalyzed by the triethylammonium ion, was found. 4. The anomalous nature of the relationship of the basicity and nucleophilicity of the carbanions of the nitro compounds with respect to carbon, observed in water, is a consequence of solvation effects.
