General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
Dimedone is an organic compound with the formula (CH 3) 2 C(CH 2) 2 (CO) 2 (CH 2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.
Dibenzoylmethane (DBM) is an organic compound with the formula (C 6 H 5 C(O)) 2 CH 2.DBM is the name for a 1,3-diketone, but the compound exists primarily as one of two equivalent enol tautomers. [2]
Acetylacetone is an organic compound with the chemical formula CH 3 −C(=O)−CH 2 −C(=O)−CH 3. It is classified as a 1,3-diketone. It exists in equilibrium with a tautomer CH 3 −C(=O)−CH=C(−OH)−CH 3. The mixture is a colorless liquid.
In organic chemistry, a ketone / ˈ k iː t oʊ n / is an organic compound with the structure R−C(=O)−R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group −C(=O)− (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' are methyl), with the formula (CH 3) 2 CO ...
Dibenzyl ketone, or 1,3-diphenylacetone, is an organic compound composed of two benzyl groups attached to a central carbonyl group. This results in the central carbonyl carbon atom being electrophilic and the two adjacent carbon atoms slightly nucleophilic.
1,3-Indandione (sometimes simply indanedione) is an organic compound with the molecular formula C 6 H 4 (CO) 2 CH 2. It is a β-diketone with indane as its structural nucleus. It is a colorless or white solid, but old samples can appear yellowish [ 3 ] or even green.
Diimines are prepared by condensation reactions where a dialdehyde or diketone is treated with amine and water is eliminated. [2] Many are derived from the condensation of 1,2-diketones and dialdehydes with amines, often anilines. [3] The dialdehyde glyoxal is an especially common precursor. Similar methods are used to prepare Schiff bases and ...
