1,3-Cyclohexanedione is an organic compound with the formula (CH 2) 4 (CO) 2. It is one of three isomeric cyclohexanediones. It is a colorless compound that occurs naturally. It is the substrate for cyclohexanedione hydrolase. The compound exists mainly as the enol tautomer. [2]
A classic example for favoring the keto form can be seen in the equilibrium between vinyl alcohol and acetaldehyde (K = [enol]/[keto] ≈ 3 × 10 −7). In 1,3-diketones, such as acetylacetone (2,4-pentanedione), the enol form is more favored. The acid-catalyzed conversion of an enol to the keto form proceeds by proton transfer from O to carbon.
Dimedone is an organic compound with the formula (CH 3) 2 C(CH 2) 2 (CO) 2 (CH 2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.
In enzymology, a cyclohexane-1,3-dione hydrolase (EC 3.7.1.10) is an enzyme that catalyzes the chemical reaction cyclohexane-1,3-dione + H 2 O ⇌ {\displaystyle \rightleftharpoons } 5-oxohexanoate Thus, the two substrates of this enzyme are cyclohexane-1,3-dione and H 2 O , whereas its product is 5-oxohexanoate .

General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
The Wichterle reaction is a variant of the Robinson annulation that replaces methyl vinyl ketone with 1,3-dichloro-cis-2-butene. This gives an example of using a different Michael acceptor from the typical α,β-unsaturated ketone. The 1,3-dichloro-cis-2-butene is employed to avoid undesirable polymerization or condensation during the Michael ...
