cyclononan4one

Cyclononan4one is a cyclic ketone with the molecular formula C9H16O. It features a nine-membered ring structure containing a carbonyl group at the fourth position. The presence of the nine-membered ring introduces some ring strain compared to smaller or larger cyclic systems, influencing its chemical reactivity and physical properties. Its synthesis typically involves established methods for forming cyclic ketones, such as intramolecular acylation reactions or oxidation of corresponding cyclic alcohols.

As a ketone, cyclononan4one undergoes characteristic reactions. It can participate in nucleophilic addition reactions at the carbonyl carbon, leading to the formation of alcohols, amines, or other derivatives. It can also undergo reactions at the alpha-carbons, such as halogenation or alkylation, under appropriate conditions. The relatively flexible nine-membered ring allows for different conformations, which can affect its stereochemical outcomes in certain reactions. Information regarding its specific uses or applications is not widely documented in general chemical literature, suggesting it is primarily a subject of academic study in organic synthesis or physical organic chemistry research rather than a common industrial chemical. Its spectroscopic data, including NMR and IR, would be crucial for its identification and characterization.
