High Performance Liquid Chromatographic Behavior of Difluoroborane Derivatives of β-Diketones

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 a...

Summary: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.
