Cycloheptanone

Cycloheptanone, also known as cycloheptan-1-one, is an organic compound in the class of cyclic ketones. Its molecular formula is C7H12O and its molecular weight is about 112.17 g/mol.

It consists of a seven-membered carbon ring with a ketone carbonyl group at one position, giving cycloheptanone’s characteristic ring-locked structure.

Preparation and occurrence: Cycloheptanone is typically prepared by oxidation of cycloheptanol or cycloheptene derivatives, and it can also be formed in oxidative rearrangements of larger cyclic compounds. It is not generally found in nature.

Reactions and uses: As a ketone, it participates in typical carbonyl reactions, including nucleophilic addition to the carbonyl group and enolization leading to alpha-functionalization. It can be reduced to cycloheptanol or converted into a variety of substituted cycloheptane derivatives, which are used as intermediates in pharmaceutical, agrochemical, and specialty chemical syntheses.

Applications: It serves as an intermediate in the preparation of cycloalkane derivatives and can be used as a solvent or research reagent in organic synthesis.

Safety: Cycloheptanone is flammable and can irritate skin, eyes, and the respiratory tract; it should be handled in a well-ventilated area with appropriate protective equipment.
