摘要
The keto-enol-enethiol tautomerism in 3-oxo-3-R1-N-R 2-propanethioamides under vacuum and in acetone was studied in terms of density functional theory. It was established that the equilibrium depends on the structure of the 3-oxo-3-R1-N-R2-propanethioamides and on the nature of the solvent, but the most stable form is as a rule the keto form stabilized by an intramolecular hydrogen bond. © 2005 Springer Science+Business Media, Inc.
