Then comes the role of intermolecular H-bonding between the adsorbate and adsorbent. This can stabilize both the keto and enol tautomers, according to the arrangements of the functional groups and the geometry of the β-diketo molecules. Acid groups on the adsorbent can enhance enolization ...

Keto-enol tautomerism is the most common tautomery phenomenon.Keto -enol themselves are the real chemical substance. 酮及烯醇互变是互变作用最普通的现象,它们都是真实的化学实体。 Keto-enol tautomerizing of ethyl acetoacetate was studied by UV.It was conformed that the content of enol ethyl acetoac...
The process whereby a hydrogen atom attached to the α−carbon of carbonyl compound moves to the carbonyl oxygen atom is known as enolization or keto-enol tautomerism. Isomeric carbonyl and enol structure are tautomers. −H∣C∣−CO//\Carbonyl⇔\/C=COH/\Enol KT=[enol][carbonyl] ...
Successful detection of a very small amount of the keto-enol tautomer is due to a high fluorescence yield of the keto-enol tautomer. The nature of the S1,(n,π*) states of the tautomers and the hydrogen-bonded complexes with water are also discussed. 展开 ...
