With strong bases, the positions 4 and 6 (the two CH 2-groups of the carbonyl group and the C-C double bond adjacent) are deprotonated. Cyclohexenone is an in-vitro catalyst for a relatively mild decarboxylation of alpha amino acids. [7] [8]
For example, the conjugate addition of methylamine to cyclohexen-2-one gives the compound 3-(N-methylamino)-cyclohexanone. Conjugated carbonyls react with hydrogen cyanide to 1,4-keto-nitriles. See hydrocyanation of unsaturated carbonyls. In the Nagata reaction the cyanide source is diethylaluminum cyanide.
Methylcyclohexanones are a group of three isomers: 2-methylcyclohexanone, 3-methylcyclohexanone, and 4-methylcyclohexanone. [1] They can be viewed as derivative of cyclohexanone. They can be prepared by oxidation of methylcyclohexane as well as partial hydrogenation of the corresponding cresols. All are colorless liquids. The 2- and 3-isomers ...
2 C 6 H 12 + O 2 → 2 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid. The oxidation involves radicals and the intermediacy of the hydroperoxide C 6 H 11 O 2 H. Alternatively, cyclohexanol can be produced by the hydrogenation of phenol ...
Cyclohexanone is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [11]. C 6 H 12 + O 2 → (CH 2) 5 CO + H 2 O. This process forms cyclohexanol as a by-product, and this mixture, called "KA Oil" for ketone-alcohol oil, is the main feedstock for the production of adipic acid.
Benzene is converted to cyclohexylbenzene by acid-catalyzed alkylation with cyclohexene. [6] Cyclohexylbenzene is a precursor to both phenol and cyclohexanone. [7] Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam. [8] The oxidative cleavage of cyclohexene gives adipic acid.

Cyclohexanehexone can be viewed as the neutral counterpart of the rhodizonate anion C 6 O 2− 6.The singly charged anion C 6 O − 6 has been detected in mass spectrometry experiments, formed by oligomerization of carbon monoxide through the formation of molybdenum carbonyls.
