Zur keto-enol-tautomerie bei heterocyclischen β-ketocarbonsäureestern—VIThe preponderance of the keto form in the keto-enol equilibrium of 2,6-dialkylsubstituted 尾-ketodicarboxylic acid esters which are not substituted at the hetero atom can be explained by steric interactions of the ...

Generally, the HOMED values decrease for the keto tautomers, particularly for the ring containing the labile proton. Even for the keto tautomers possessing energetic parameters close to those of the enol isomers, the HOMED indices are low. However, some kind of parallelism exists for the keto...
NMR-spektroskopische Untersuchung der Keto-Enol-Tautomerie von AcetessigsäureamidenBased on the differing chemical shifts of the CH- versus the CH 2 -groups, and the methyl groups of the keto versus the methyl groups of the enol form of the acetoacetamides, it is possible to study the ...
The degree of enol formation was calculated on the basis of the excess Gibbs free energy of mixing and the static relative permittivity. It was found that the results obtained exclusively from dielectric data ( and 位) show a good agreement with those calculated from the thermodynamic model....

Whereas all investigated 3-(arylthio)isochromane-1,4-diones 3 are completely enolized their S , S -dioxides 7 show, depending on the solvent, keto-enol equilibria in which the keto species are dominating (IR, UV VIS, 1H, and 13C measurements). Some characteristic properties of these ...
