4,4'-difluorobenzophenone
Sign in to save4,4’-Difluorobenzophenone is an organic compound with the formula of (FC6H4)2CO. This 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.

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. FC6H4C(O)Cl + C6H5F → (FC6H4)2CO + HCl
