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 classes of compounds are dis...

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 ...

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 ...

The modelling of the mixture was also made in the form of an A + A2 + B type ternary mixture using the vapour-liquid equilibrium data of the cyclohexanone + carbon tetrachloride mixture. The degree of enol formation was calculated on the basis of the excess Gibbs free energy of mixing and...
