Enol meaning chemistry
WebJul 31, 2024 · The enol form of 2,4-pentanedione (and of related dicarbonyl compounds of the type ) not only is stabilized by electron-delocalization, as shown in Structures 4a and 4b, but by hydrogen-bonding of the acidic hydrogen between the two oxygens: Of course, such stabilization is not possible for the keto form. In organic chemistry, alkenols (shortened to enols) are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene (olefin) with a hydroxyl group attached to one end of the alkene double bond (C=C−OH). The terms enol and alkenol are portmanteaus deriving from "-ene"/"alkene" … See more Organic esters, ketones, and aldehydes with an α-hydrogen (C−H bond adjacent to the carbonyl group) often form enols. The reaction involves migration of a proton from carbon to oxygen: In the case of … See more Phenols represent a kind of enol. For some phenols and related compounds, the keto tautomer plays an important role. Many of the reactions of resorcinol involve the keto tautomer, for … See more Addition of electrophiles The terminus of the double bond in enols is nucleophilic. Its reactions with electrophilic organic … See more If R and R (note equation at top of page) are different substituents, there is a new stereocenter formed at the alpha position when an enol converts to its keto form. Depending on the … See more Enediols are alkenes with a hydroxyl group on each carbon of the C=C double bond. Normally such compounds are disfavored … See more Keto–enol tautomerism is important in several areas of biochemistry. The high phosphate-transfer potential of phosphoenolpyruvate results … See more In general, enols are less stable than their keto equivalents because of the favorability of the C=O double bond over C=C double bond. However, enols can be stabilized kinetically … See more
