A fluorinated β-diketone building block

Used as a synthesis intermediate for metal complexes, isoxazoles, pyrimidine and pyrazoles in application of OLEDs, displays, and drug discovery

Specifications | MSDS | Literature and Reviews

2-Furoyltrifluoroacetone (CAS number 326-90-9) is a derivative of β-diketone with a furan and a trifluoromethyl substituents. 2-Furoyltrifluoroacetone is directly applied as a ligand to the synthesis of luminescent terbium (Tb III) and lanthanide (Ln III) complexes that are used OLEDs and displays. The complexes have high quantum efficiency of 77% and long lifetime of 842 μs.

The furan of 2-Furoyltrifluoroacetone can be easily modified via Diels-Alder reactions (with electron deficient dienophiles) and electrophilic substitution.

The β-diketone (1,3-diketone) moiety is a precursor for many other heterocyclic compounds. 2-Furoyltrifluoroacetone reacts with hydrazine to form pyrazole, with hydroxylamine to form isoxazole, and with urea pyrimidine. The heterocyclic compounds are investigated as active pharmaceutical ingredients (APIs) for anticancer and anti-inflammatory drug discovery.
