Condensation of aromatic aldehydes with 3(8)-acetyl-4(7)-difluoroboryloxycoumarin intramolecular complexes gave boron complexes of α,β-unsaturated ketones, whose hydrolysis afforded the corresponding hydroxy cinnamoylcoumarins. The boron complexes and their hydrolysis products intensely absorb and fluoresce in the visible region of the spectrum.
