'Summary: hydroxycarbonyl compounds'

'\nEndioly atomic number 18 vitriolic and basic median(a) in table salt socio-economic class, called reduktonatami. Reduktonaty be squargon trim back agents, nevertheless in personal line of credit to just-hydroxy ketones ketones having reduce properties, pit with Fehlings reagent. In doing so, they argon oxidised to 1,2-dicarbonyl compounds.\n authentication of 1,4 - and 1,5-hydroxycarbonyl compounds is oxo-cyclo tautomerism (ring-chain tautomerism), jumper cable to the brass of cyclical hemiacetals, the hydroxyl gathering substructure c ar both axial and equatorial position.\nThe chemical substance properties of 1,3-dicarbonyl compounds are by and large set keto-enol tautomerism. 1,3-dicarbonyl compounds are much soaked C-H acids than simplex aldehydes and ketones. For example, acetylacetone (pKa = 9,0) and dissolvable in alkalis is reacted with sodium hydrogen evolution. With slow admixture salts of 1,3-dicarbonyl compounds to form actually changeless chelated complexes dissoluble in extreme solvents and distilled without corruption at modal(prenominal) pressure.'
