DNA Structure and Function
Thymine (enol) . Guanine Cytosine (imino) . Adenine (the unpaired electrons of
the oxygen and nitrogen) represent hydrogen bonding acceptors. The enol
configuration can exist rarely, at a frequency of about 10~4. Here a hydrogen
moves ...

Modern Physical Organic Chemistry
For normal alkyl ketones and aldehydes, there is a miniscule fraction of the enol
present at equilibrium. However, in 3-diketones the enol form becomes a
significant fraction of the equilibrium. This is because the creation of a conjugated
it ...

Essentials of Pharmaceutical Chemistry
Warfarin is an interesting compound in that, in addition to ionising, it exhibits keto
— enol tautomerism. This means that warfarin exists in two constitutional
isomeric forms (tautomers) that are in equilibrium with each other, although one
of the ...

Introduction to Spectroscopy
For most 1,3-dicarbonyl compounds, the equilibrium lies substantially to the right,
favoring the enol. The enol form is stabilized through the formation of a strong
intramolecular hydrogen bond. Note that both methyl groups are equivalent in the
...
