Eksempler på bruk av ENOLS i en setning

• The Knoevenagel condensation and they allow keto acids serve as a stabilizing protecting group for carboxylic acid enols.
• Although such a shift is symmetry allowed, the Mobius topology required in the transition state prohibits such a shift because it is geometrically impossible, which accounts for the fact that enols do not isomerize without an acid or base catalyst.
• He enunciated the principle of vinylogy which is now taught in terms of resonance in valence bond theory, elucidated the mechanism of the conjugate addition of Grignard reagents to unsaturated carbonyls compounds, and discovered stable enols and enediols of sterically hindered molecules.
• Carbonyl compounds, being carbon acids, can also be deprotonated to form enolates, which are much more nucleophilic than enols or enol ethers and can attack electrophiles directly.
• As selenoxides can be readily prepared from nucleophilic carbonyl derivatives (enols and enolates), selenoxide elimination has grown into a general method for the preparation of α,β-unsaturated carbonyl compounds.
• "Kinetic Protonation of Enols, Enolates and Analogs; The Stereochemistry of Ketonization," Zimmerman, H.
• Enols can be fluorinated enantioselectively (see above) in the presence of a chiral fluorinating agent.
• The unsaturated tetrachloride hydrolyzes to enols that tautomerize to the bis-dione, which in turn can be oxidized to the tetracarboxylic acid.
