    Abstract: Quinones may be perfluoroalkylated by means of perfluoroalkyltrihydrocarbyl silane using quaternary ammonium bifluorides, quaternary phosphonium bifluorides or alkali metal bifluorides as catalysts. The reaction--which is conducted under essentially anhydrous conditions, preferably in a suitable liquid phase reaction medium, most preferably a dipolar aprotic solvent--results in the formation of gem-disubstituted cyclohexadienones in which the gem substituents are a perfluoroalkyl group and a trihydrocarbylsiloxy group. These gem-disubstituted compounds in turn can be readily converted to perfluoroalkyl substituted aromatics, thus circumventing the traditional need for photochlorination followed by halogen exchange using hydrogen fluoride as a means of preparing perfluoroalkyl aromatic compounds.
