20.500.12556/DiRROS-29108 Acetylacetone metal complexes and keto-enol tautomerism – which tautomer is more/less stable? Acetylacetone Tautomerism is a fundamental concept that studies the transfer of a proton between two constitutional isomers, i.e. keto and enol tautomers, where the enol tautomers are usually less stable than the corresponding carbonyl compound. However, this is not the case with acetylacetone. This article discusses two rapidly inter-converting tautomeric forms of acetylacetone, the archetypal (and now textbook) example of tautomerism in organic chemistry from a thermochemical perspective. Tavtomerizem je temeljni koncept, ki raziskuje prehajanje protona med dvema konstitucionalnima izomeroma, to je keto in enolnim tavtomerom. Enolni tavtomeri so navadno manj stabilni kot ustrezne karbonilne spojine, vendar pa to ne velja za acetilaceton. Ta članek s termokemijskega vidika obravnava hitro prehajanje keto oblike acetilacetona v enolno obliko, ki predstavlja arhetipski (in učbeniški) primer tavtomerizma v organski kemiji. keto-enol acetylacetone acetilaceton true false true Slovensko kemijsko društvo Slovenija Angleški jezik Slovenski jezik Copyright (c) 2025 Maja Ponikvar-Svet, Kathleen F.
