It is a white crystalline powder that has a high solubility in water. Its pKa of 1.48 indicates that it is a strong acid.〔Prakash, G. K. S.; Hu, J. "Pentafluorobenzoic Acid" e-EROS Encyclopedia of Reagents for Organic Synthesis, 2005. 〕 == Preparation== Pentafluorobenzoic acid is prepared by treating pentafluorophenyllithium (or pentafluorophenyl Grignard reagent) with carbon dioxide. These reagents are usually prepared in situ from pentafluorobenzene and bromopentafluorobenzene.〔 It arises via the reaction of perfluorotoluene with trifluoroacetic acid and antimony pentafluoride.〔Yaroslav V.
