tautomerism , auch: dynamic isomerism

An example of this type of tautomerism can be found in bullvalene.

Keto-enol tautomerism is important in several areas of biochemistry.

Prototropic tautomerism may be considered as a subset of acid-base behavior.

The Keto-enol tautomerism strongly depends on the solvent used for the experiments.

This lactam lactim tautomerism can also be found in other molecules with a similar structure.

Keto-enol tautomerism is catalyzed by either acid or base.

His focus gradually shifted from the structure of pyrazoles to the more general concept of tautomerism.

He coined the expression tautomerism in 1885.

Certain triazoles are relatively easy to cleave due to so-called ring-chain tautomerism.

The concept of tautomerizations is called tautomerism.

Prototropy is the most common form of tautomerism and refers to the relocation of a proton.

Protonation leads through Keto-enol tautomerism to the saturated carbonyl compound.

The enediol structure is stabilized by the resonance resulting from the tautomerism with the adjacent carbonyl.

It is distinct from prototropic tautomerism, and involves processes with rapid reorganisation of bonding electrons.

Ethyl acetoacetate is subject to Keto-enol tautomerism.

This is called keto-enol tautomerism.

Linstead was a pioneer in the chemistry of phthalocyanine dyes and studied allylic tautomerism.

In keto-enol tautomerism, enols interconvert with ketones or aldehydes.

Valence tautomerism requires a change in molecular geometry and should not be confused with canonical resonance structures or mesomers.

The reduced phosphorus acids are subject to similar tautomerism involving shifts of H between O and P.

The enamine-imine tautomerism may be considered analogous to the keto-enol tautomerism.

According to his account, he wrote a thesis in 1919 in which the H-bond was introduced and applied to tautomerism in acetoacetic acid.

One of the early investigators into keto-enol tautomerism was Richard August Carl Emil Erlenmeyer.

It is also used in physical chemical studies involving metal complex binding, hydrogen bonding, and tautomerism and proton transfer effects in nucleobases.

Resonance is distinguished from tautomerism and conformational isomerism, which involve the formation of isomers, thus the rearrangement of the nuclear positions.
