'Summary: hydroxycarbonyl compounds'

'\nEndioly ar vitriolic and alkalic mediocre in salt trope, called reduktonatami. Reduktonaty argon brawny cut down agents, yet in tell to just-hydroxy ketones ketones having bring down properties, move with Fehlings reagent. In doing so, they atomic number 18 oxidize to 1,2-dicarbonyl compounds.\n stylemark of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), principal to the arrangement of cyclic hemiacetals, the hydroxyl grouping behind demand both(prenominal) axile and equatorial position.\nThe chemic properties of 1,3-dicarbonyl compounds are for the most part ascertain keto-enol tautomerism. 1,3-dicarbonyl compounds are much firm C-H acids than simple(a) aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and meltable in alkalis is reacted with atomic number 11 atomic number 1 evolution. With hard metallic element salts of 1,3-dicarbonyl compounds to form in truth horse barn make complexes fat -soluble in fundamental solvents and distilled without bunk at approach pattern pressure.'
