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]
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 .
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 ...
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.

1,5-Pentanediol, a common plasticizer and precursor to polyesters is manufactured by hydrogenation of glutaric acid and its derivatives. [3] Glutaric acid itself has been used in the production of polymers such as polyester polyols, polyamides. The odd number of carbon atoms (i.e. 5) is useful in decreasing polymer elasticity. [4]
The periselectivity of a particular reaction depends on the structure of both the ketene and the substrate. Although the reaction is predominantly used to form four-membered rings, a limited number of substrates undergo [3+2] or [4+2] reactions with ketenes. Examples of all three modes of cycloaddition are discussed in this section.
1,4-Cyclohexadiene is an organic compound with the formula C 6 H 8. It is a colourless, flammable liquid that is of academic interest as a prototype of a large class of related compounds called terpenoids, an example being γ-terpinene. An isomer of this compound is 1,3-cyclohexadiene.
