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 ...

The Debus–Radziszewski imidazole synthesis is a multi-component reaction used for the synthesis of imidazoles from a 1,2-dicarbonyl, an aldehyde, and ammonia or a primary amine. The method is used commercially to produce several imidazoles. [1] The process is an example of a multicomponent reaction. The reaction can be viewed as occurring in ...
A ketone compound containing a carbonyl group (C=O) In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom.
Following rearrangement and loss of water, a second equivalent of water attacks the alpha position. Red amorphous selenium is liberated in the final step to give the 1,2-dicarbonyl product. [8] [9]: 4331 Allylic oxidation using selenium-dioxide proceeds via an ene reaction at the electrophilic selenium center.
Kethoxal, as with other 1,2-dicarbonyl compounds, [5] reacts with nucleic acids. It has high specificity for guanine over other ribonucleotides.In whole RNA, it reacts preferentially with guanine residues that are not involved in hydrogen-bonding.
The Isay reaction also known as Gabriel-Isay condensation is an organic reaction in which certain diaminopyrimidines are transformed into pterins by condensation with a 1,2-dicarbonyl compound, such as 2,3-butanedione. [1] [2] The reaction is named after Oskar Isay.
Dicarbonyl(acetylacetonato)rhodium(I) is an organorhodium compound with the formula Rh(O 2 C 5 H 7)(CO) 2. The compound consists of two CO ligands and an acetylacetonate. It is a dark green solid that dissolves in acetone and benzene, giving yellow solutions. The compound is used as a precursor to homogeneous catalysts. [2]
