The principal diketone is diacetyl, also known as 2,3-butanedione, CH 3 C(O)C(O)CH 3. 1,2-Diketones are often generated by oxidation (dehydrogenation) of the diols : [ 1 ] RCH ( OH ) CH ( OH ) R RC ( O ) C ( O ) R + 2 H 2 {\displaystyle {\ce {RCH(OH)CH(OH)R -> …

The three types are referred to as linear β-diketones (lbdk), cyclic β-diketones (cbdk), and double-bond β-diketones (dbdk). In addition, triketones are also included, as the diketone motif is present. Derivatives not containing the diketo part are not considered, as this will be too extensive and is also the case for metal complexes. Figure 1.

β-二羰基化合物（英語： β-Dicarbonyl Compound ）是一类具有-C(O)CH 2 C(O)-结构的有机化合物，其中最常见的是β-二酮（英語： β-diketone ），这类化合物具有烯醇 互变异构，两个羰基间的氢具有明显的酸性。

2024年12月1日 · The β-diketone scaffold is an essential building block for COX-2 inhibitors, these inhibitors are a class of non-steroidal anti-inflammatory drugs (NSAIDs) known as coxibs. These inhibitors have demonstrated remarkable potential as anticancer agents during the preclinical stage of research [121].

2023年11月10日 · Here, barley (Hordeum vulgare) wax analyses reveal β-diketone and associated 2-alkanol ester profiles suggesting a common C16 3-ketoacid precursor.

α-二酮（α-diketone）分子中两个羰基相邻的二元酮，其结构为1，2-二羰基结构，反应活性中心多，是重要的有机合成中间体。 α-二酮类化合物是合成咪唑类、喹喔啉和吲哚酮氮氧化合物等重要的精细化学品 的重要中间体，同时其本身就普遍存在于许多天然产物和 ...

2025年1月16日 · Aqueous Zn ion batteries (AZIBs) have emerged as a promising option for energy storage on a large scale. However, the unsteady electric double layer (EDL) that causes the continuous H 2 O and SO 4 2− induced side reactions and byproducts, results in unstable anode electrolyte interphase (AEI) and restricts the practical application of AZIBs. A novel EDL reconstruction strategy is proposed by ...

By replacing the methyl groups of 2,4-pentanedione with tert-butyl groups, a diketone is obtained which, with many metals including transition and rare-earth metals, forms complexes that often are highly soluble in nonpolar organic solvents. The interior of these chelates is saltlike but the exterior is hydrocarbonlike and nonpolar, which ...
