enol

 [e´nol]
an organic compound in which one carbon of a double-bonded pair is also attached to a hydroxyl group, thus a tautomer of the ketone form. The term is also used as a prefix or infix, often italicized.

e·nol

(ē'nol),
A compound possessing a hydroxyl group (alcohol) attached to a doubly bonded (ethylenic) carbon atom (-CH=CH(OH)-); properly italicized when attached as a prefix or infix to an otherwise complete name, for example, enolpyruvate, phosphoenolpyruvate; usually in equilibrium with its keto tautomer.

Considering the most stable forms of hydrated [beta]-amino ketones, our computations indicated lowering of the free energies of enolization, suggesting higher equilibrium concentration of the enol forms in the presence of water.
A reacao do trimetilsilil enol eter da D-canfora 118 [55a], preparado a partir do endo-(+)-3-bromo-Dcanfora [31b], com o cloreto de dimetilmetilenoamonio [56] forneceu uma mistura entre os isomeros endo/exo numa razao de 15:85 (Esquema 56) [41a].
Our gas-phase calculations (see Table 4) indicate that for the studied model compounds the required sum of substituent constants [[sigma]sub.F] should be 1.3 (two nitro substituents) or higher for the enol form to be more stable than the phosphoryl form.
Samples of DC561 and ENOL C transformer fluids were tested by the itt route of administration, and results of these investigations are presented in Figure 4.
Indeed, spectral measurements of the film after its heating at 60[degrees]C for 50 min showed that the thermal recovery by proton back-transfer in the usual enol form occurred into a proportion of around 50% (Fig.

There have been a number of synthetic applications involving the use of enol phosphates and some correlates (e.g., phosphonates and phosphonites) as starting materials for the conversion into a variety of functional groups [2,1117].
On one hand, it could mean that the sulfate is linked to an enol in the 3 or 17 position.
Moreover, compound 4 may exist in four possible tautomeric forms, namely the enol form A, the keto form D, the enol-keto form C and the keto-enol form B as shown in Scheme-2.
The chemical basis for enhanced adhesion between polymer layers resulting from corona treatment may be due to hydrogen bonding between the -OH of enol groups and other oxygen containing functional groups created on the polymer surface by the treatment.
