Aldol reaction - Wikipedia

The aldol reaction may proceed by two fundamentally different mechanisms. Carbonyl compounds, such as aldehydes and ketones, can be converted to enols or enol ethers. These species, being nucleophilic at the α-carbon, can attack especially reactive protonated carbonyls such as protonated aldehydes. This is the 'enol mechanism'.

Chapter 15: Aldehyde and Ketones - chem.latech.edu

Aldehydes and ketones exists in two different isomers also called tautomers. Regular carbonyl form of the aldehyde or the ketone is called keto form and the -OH containing form is called enol from. In biological systems keto form of aldehyde sugars (aldoses) are converted to ketone sugars (ketoses) via enediol (enol) form as shown below.

Alcohol oxidation - Wikipedia

Alcohol oxidation is an important organic reaction. Primary alcohols (R-CH 2-OH) can be oxidized either to aldehydes (R-CHO) or to carboxylic acids (R-CO 2 H), while the oxidation of secondary alcohols (R 1 R 2 CH-OH) normally terminates at the ketone (R 1 R 2 C=O) stage. Tertiary alcohols (R 1 R 2 R 3 C-OH) are resistant to oxidation.

Apr 25, 2009 · Ketones can not be directly converted into aldehydes. A ketone, has a carbonyl group (C=O) with two R groups attached on either side (R can not be hydrogen). An aldehyde, has a carbonyl group, with only ONE R group attached. The other atom attached to .

Aldehydes and ketones: Reactions of enolate ions

In the presence of sodium hydroxide, aldehyde or ketone is converted to an enolate ion, but not all the carbonyl molecules are converted and so the enolate ion can undergo a nucleophilic addition on 'free' aldehyde or ketone. The product is a β-hydroxyaldehyde or β-hydroxyketone. Aldehy-des react better than ketones in this reaction.
