General description
1,5-Diphenyl-1,3,5-pentanetrione (H2DBA, DBAc) is a symmetrical triketone.1,3,5-triketones are potential tridentate ligands and forms complexes with transition metals, lanthanides and actinides. It acts as ligand and forms binuclear cobalt complex with CoCl2.6H2O.[1] The interaction of two intramolecular hydrogen bonds in 1,5-diphenyl-1,3,5-pentanetrione has been studied.[2] H2DBA can be synthesized by condensation reaction between ethyl benzoate and benzoyl acetone.[3] DBAc arranged in stretched polyethylene (PE) sheets has been investigated by infrared linear dichroism (LD) spectroscopy.[4]
