If a dynamic equilibrium is established between the two isomers it is also referred to as valence tautomerism.
12.
They are tautomeric and can exist as number of tautomers ( keto-enol tautomerism ), here exemplified by piroxicam:
13.
The tautomerism of the norcaradiene and cycloheptatriene can be understood based on the Walsh cyclopropane molecular orbitals of the norcaradiene cyclopropane ring.
14.
For instance, in the field of heterocyclic chemistry, of mainly azoles, he has studied tautomerism, hydrogen bonding and aromaticity.
15.
It is also used in physical chemical studies involving metal complex binding, hydrogen bonding, and tautomerism and proton transfer effects in nucleobases.
16.
The C = C double bond with adjacent thiol gives thioenols and enedithiols their chemical characteristics, by which they present keto-enol tautomerism.
17.
According to his account, he wrote a thesis in 1919 in which the H-bond was introduced and applied to tautomerism in acetoacetic acid.
18.
The interconversion of the two forms involves the movement of an alpha hydrogen and the shifting of bonding electrons; hence, the isomerism qualifies as tautomerism.
19.
Although it is a complicated concept, tautomerism is relevant to the behavior of amino acids and nucleic acids, two of the fundamental building blocks of life.
20.
This was done through the determination of the Enol content in Keto-Enol-tautomerism equilibria via titration of bromine ( Ueber die Keto-Enol Tautomerie ).
