1,3-Cyclopentanedione is an organic compound with the formula (CH 2) 3 (CO) 2. It is one of two isomeric cyclopentanediones, the other being 1,2-cyclopentanedione. The enol is predicted to be about 1-3 kcal/mol more stable than the diketo form. [1] The enol structure has been confirmed by X-ray crystallography. [2]
Cyclohexa-1,3-diene is an organic compound with the formula (C 2 H 4)(CH) 4. It is a colorless, flammable liquid. Its refractive index is 1.475 (20 °C, D).
1,3-Cyclobutanedione is an organic compound with the formula (CH 2) 2 (CO) 2. It is an isomer of 1,2-cyclobutanedione. The compound would be of little interest except that its tautomer is a subunit in some commercial dyes. In solution, 1,3-cyclobutanedione exists in equilibrium with a less stable tautomer, called squaraine, 3-hydroxycyclobut-2 ...

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.
A related classic synthesis for cycloheptatriene derivatives, the Buchner ring enlargement, starts with the reaction of benzene with ethyl diazoacetate to give the corresponding norcaradiene ethyl ester, which then undergoes a thermally-allowed electrocyclic ring expansion to give 1,3,5-cycloheptatriene 7-carboxylic acid ethyl ester.
