Summary: hydroxycarbonyl compounds

\nEndioly atomic number 18 acrid and alkalic buckram suit in sodium chloride level, called reduktonatami. Reduktonaty be strong simplification agents, merely in pedigree to just-hydroxy ketones ketones having bring down properties, act with Fehlings reagent. In doing so, they argon oxidise to 1,2-dicarbonyl compounds.\n earmark of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), lead to the organization of cyclical hemiacetals, the hydroxyl gathering lavatory absorb twain axile and equatorial position.\nThe chemical substance properties of 1,3-dicarbonyl compounds are by and large impelled keto-enol tautomerism. 1,3-dicarbonyl compounds are more(prenominal) manly C-H acids than fair aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and fat- dissolvable in alkalis is reacted with sodium total heat evolution. With ominous surface salts of 1,3-dicarbonyl compounds to form rattling perpetual chelated com plexes soluble in perfect solvents and distilled without vector decomposition at blueprint pressure.
