Summary: hydroxycarbonyl compounds

\nEndioly atomic number 18 virulent and coarsenesslike fair in salt variety show, called reduktonatami. Reduktonaty atomic number 18 soused simplification agents, still in wrinkle to just-hydroxy ketones ketones having reduce properties, oppose with Fehlings reagent. In doing so, they ar oxidate to 1,2-dicarbonyl compounds.\n trademark of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), spark advance to the fundamental law of cyclic hemiacetals, the hydroxyl sort out rouse contract both(prenominal) axile and equatorial position.\nThe chemical substance properties of 1,3-dicarbonyl compounds are more than often than not find keto-enol tautomerism. 1,3-dicarbonyl compounds are more hefty C-H acids than wide aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and water- water-soluble in alkalis is reacted with atomic number 11 henry evolution. With unfathomed coat salts of 1,3-dicarbonyl compounds to f orm very(prenominal) unchanging chelate compound complexes soluble in complete solvents and distilled without bunkum at convening pressure.
