[Chemical Properties]

yellow fine crystalline powder
[Uses]

Reactant involved in:
  • Synthesis of β-1,3-dicarbonyl aldehydes via oxidation
  • Knoevenagel condensation using a lysine catalyst
  • Cycloisomerization fo rthe synthesis of trisubstituted furans
  • Fluorination by HF and iodosylbenzene
  • Intramolecular Michael addition reactions for synthesis of benzylbutyrolactones
  • Synthesis of diols via reduction of aromatic and aliphatic ketos esters
  • Cross-coupling reactions for stereoselective synthesis of unsymmetrical 1,4-enediones
[Uses]

It is employed as a reactant involved in synthesis of β-1,3-dicarbonyl aldehydes via oxidation, knoevenagel condensation using a lysine catalyst, and cycloisomerization for the synthesis of trisubstituted furans. It is also a reactant for the fluorination by HF and iodosylbenzene, intramolecular Michael addition reactions and synthesis of diols. Also applied in the synthesis of diols via reduction of aromatic and aliphatic ketos esters6 and cross-coupling reactions for stereo selective synthesis of unsymmetrical 1,4-enediones.
