Enol - Wikipedia
网页Enols are a type of functional group or intermediate in organic chemistry with the formula R2C=CROH. Enolization is the reaction of proton migration from carbon to oxygen, which occurs in ketones, aldehydes and esters with an α-hydrogen.

Enolates – Formation, Stability, and Simple Reactions
网页2022年8月16日 · 1. What Is An Enolate Ion? Aldehydes and ketones will react with strong base [e.g. HO (-) ] to give an enolate ion. A C-H bond is broken on the carbon adjacent to the carbonyl carbon (i.e. the “alpha-carbon”). The carbons further away from the carbonyl are never deprotonated.
