}}
4,4’-Difluorobenzophenone is an organic compound with the formula of (FC6H4)2CO. This a colorless solid is commonly used as a precursor to PEEK, or polyetherether ketone, a so-called high performance polymer. Because PEEK is resistant to attack, it is commonly used in carbon fiber coatings and cable insulation.
==Synthesis==
4,4’-Difluorobenzophenone is prepared by the acylation of fluorobenzene with ''p''-fluorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent.
:FC6H5C(O)Cl + C6H5F → (FC6H4)2CO + HCl
