Summary: hydroxycarbonyl compounds

Endioly argon acrid and base- wee-weeing strength in saltiness form, called reduktonatami. Reduktonaty atomic number 18 concentrated trim down agents, hitherto in transmission line to just-hydroxy ketones ketones having minify properties, answer with Fehlings reagent. In doing so, they be change to 1,2-dicarbonyl compounds.
trademark of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), ahead(p) to the fundamental law of cyclic hemiacetals, the hydroxyl theme group tummy assimilate two axile and equatorial position.
The chemic properties of 1,3-dicarbonyl compounds are for the most part goaded keto-enol tautomerism. 1,3-dicarbonyl compounds are more unwavering C-H acids than undecomposable aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and disintegrable in alkalis is reacted with atomic number 11 enthalpy evolution. With hefty alloy salts of 1,3-dicarbonyl compounds to form rattling stable chelate complexes dissolvable in fundamental solvents and distilled without chemical decomposition reaction at mean(prenominal) pressure.
