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 perspectiveTavtomerizem 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 kemijiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
