Hexenone

Hexenone is a general term used in organic chemistry to describe a class of unsaturated ketones that contain a six-carbon chain and at least one double bond. Specifically, a hexenone features a carbonyl group (C=O) within a six-carbon framework, with the presence of one or more carbon-carbon double bonds (C=C) along this chain. The position of the double bond(s) and the carbonyl group dictates the specific isomer. For instance, hex-2-en-1-one refers to a six-carbon chain with a double bond between the second and third carbons and a carbonyl group at the first carbon.

These compounds are found in various natural products and are often synthesized in laboratories for research purposes or as intermediates in the synthesis of more complex molecules. Their reactivity is influenced by both the carbonyl group and the double bond, allowing for a range of chemical transformations. Reactions involving hexenones can include nucleophilic addition to the carbonyl, electrophilic addition to the double bond, or Diels-Alder reactions. The stereochemistry of the double bond (cis or trans) can also play a significant role in the compound's properties and reactivity.
