Encyclopedia > Diketone

A diketone is a molecule containing two carbonyl groups. In chemistry, a carbonyl group is a functional group composed of an atom of carbon double-bonded to an atom of oxygen. ...


A diketone is an oxygen nucleophile.


Reactions

Diketones react similarly to ketones or aldehydes. A ketone is either the functional group characterized by a carbonyl group linked to two other carbon atoms or a compound that contains this functional group. ... An aldehyde is either a functional group consisting of a terminal carbonyl group, or a compound containing a terminal carbonyl group. ...


They are also called multiketones. They were first found out by famous Chinese medic Chi-Chiao Zaliban, in 1765 B.C. Bascally, he drank it and died, and his lat words were ke-ton, which on chinese mean f*** off. Whoooops!!!!!!!!


They also readily undergo enolization, and many 1,3-diketones are thermodynamically stable as conjugated enols or even enolates. One such is ascorbic acid, which is more stable as an enol rather than a diketone. The enol group gives off a proton, and the charge of the resulting enolate is delocalized along the ketone-enolate system. This delocalization stabilizes the enolate counterion and makes it less likely to regain the proton, which makes ascorbic acid acidic. This article deals with the molecule ascorbic acid in General, for the nutrient see Vitamin C Ascorbic acid is an organic acid with antioxidant properties. ...


Nucleophilic addition

diketone + nucleophiletetrahedral carbonyl addition compound In organic chemistry, a nucleophilic addition reaction is an addition reaction where in a chemical compound a pi bond is removed by the creation of two new covalent bonds by the addition of a nucleophile. ... In chemistry, a nucleophile (literally nucleus lover) is a reagent which is attracted to centres of positive charge. ... A tetrahedral carbonyl addition compound is an organic compound formed by nucleophilic addition to a carbonyl compound such as an aldehyde or ketone. ...

diketone: Definition and Much More from Answers.com (326 words)
A diketone is a molecule containing two carbonyl groups.
One such is ascorbic acid, which is more stable as an enol(ate) rather than a diketone.
Also, if a diketone has ketone carbonyls separated only by one carbon, the alcohol hydrogen in the corresponding enol is hydrogen-bonded to the carbonyl oxygen, giving a six-membered ring (-RC=CH-OH..O=CR-).
