2-Acetylcyclohexanone is used in the synthesis of 1-(pyridyl)ethanol derivatives that can reduce keto-esters and ketones. Also used in the synthesis of phenothiazine derivatives that can inhibit prote in farnesyltransferase molecules and some that show anti-proliferative activity.

?? ??

The keto-enol tautomerism of 2-acetylcyclohexanone (ACHE) in water was studied.

Purification Methods

Dissolve it in ligroin (b 30-60o), wash it with saturated aqueous NaHCO3, dry over Drierite and fractionate in a vacuum. [Perfetti & Levine J Am Chem Soc 75 626 1953, Manyik et al. J Am Chem Soc 75 5030 1953, Eistert & Reiss Chem Ber 87 108 1954.] It forms a Cu salt which crystallises in green leaflets from EtOH, m 162-163o [UV: McEntee & Pinder J Chem Soc 4419 1957].
