2,3-Pentanedione (acetylpropionyl) is one of the aroma active compounds of cereal coffee brew.

Applicazioni

2,3-Pentanedione can be used as a reactant to synthesize:
  • Bisphenol derivatives by acid-catalyzed condensation reaction with phenols.
  • 2-Ethyl-3-methyl-1H-indole by Pd-catalyzed reaction with aniline under reductive conditions.
  • 2-Ethyl-3-methylquinoxaline by condensation reaction with o-phenylenediamine using citric acid as a catalyst.
