Solvent effect on the rate of the Mannich reaction of butyraldehyde with formaldehyde

Article abstract of DOI:10.1134/S1070428006090028

The Mannich reaction of formaldehyde with butyraldehyde and diethylamine in hydrophilic solvents ensuring homogeneity of the medium follows the kinetic relations typical of an irreversible second-order reaction. The rate constants are determined by the ability of solvents to undergo self-association and their electrophilic solvation power; additional inclusion of the solvent polarity via multiparameter Koppel'-Pal'm equation is necessary to obtain a satisfactory quantitative correlation.
