4,4-DIFLUORO-1-PHENYL-1,3-BUTANEDIONE Usage And Synthesis

Uses

4,4-Difluoro-1-phenyl-1,3-butanedione (DPBD) may be used as a ligand to form the following metal complexes:

• Eu(DPBD)3·H2O
• Eu(DPBD)3·biq (biq= 2,2-biquinoline)
• Eu(DPBD)3·phen (phen= 1,10-phenanthroline)
• Eu(DPBD)3·neo (neo= neocuproine)
• Eu(DPBD)3·bipy (bipy= 2,2-bipyridyl)
• Gd(DPBD)3·(H2O)2

General Description

4,4-Difluoro-1-phenyl-1,3-butanedione (DFPB) is a fluorinated β-diketone ligand that can be prepared by reacting acetophenone with methyl-difluoroacetate.
