β-Diketones react with boron trifluoride (BF₃) under mild reaction conditions to give their difluoroborane (BF₂) chelates quantitatively. The complexes gave sharp peaks on both normal- and reversed-phase high performance liquid chromatography (HPLC), while the unreacted β-diketones gave broad peak and poor reproducibility probably due to keto-enol interconversion during the separation. Fe(III) chelate of acetylacetone (Haa) was also found to react with BF₃ to give the BF₂ chelates quantitatively.
