Ionization constants of some hydroxy-pyrones at 25 °C

Abstract

The ionization constants of some hydroxy-pyrones have been measured in aqueous solutions by a spectrophotometric method and compared with those of analogous phenols. The strikingly high acidity of 3,5-diacetyl-4,6-dihydroxy-2-pyrone has been explained by the formation of a symmetrical and extensively resonance-stabilized monoanion through ionization of the C-6 hydroxy-group.
