Pentafluoropropionic acid is used as an efficient catalyst for the preparation of dibenzo[a, j] xanthenes by condensation reaction of beta-naphthol with aryl aldehydes.
The K salt is a convenient alternative to iodopentafluoroethane for the conversion of aryl bromides and iodides to their pentafluoroethyl derivatives, avoiding sealed-tube chemistry: Synth. Commun., 18, 965 (1988):
