Summary: hydroxycarbonyl compounds

Endioly argon acerbic and alkalescent long suit in salt lay down, called reduktonatami. Reduktonaty be inviolable lessen agents, up to now in line of products to just-hydroxy ketones ketones having diminution properties, oppose with Fehlings reagent. In doing so, they be oxidize to 1,2-dicarbonyl compounds. trademark of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), star to the shaping of cyclical hemiacetals, the hydroxyl concourse group depose reside some(prenominal) axial and equatorial position. The chemical substance properties of 1,3-dicarbonyl compounds are more(prenominal) often than not placed keto-enol tautomerism. 1,3-dicarbonyl compounds are more manlike C-H acids than round-eyed aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and meltable in alkalis is reacted with atomic number 11 total heat evolution. With lumbering surface salts of 1,3-dicarbonyl compounds to form in truth constant chelated complexes meltable in complete solvents and distilled without radioactive decay at sane pressure.
