Gem-disubstituted cyclohexadienones and their production |
| abstract |
Gem-disubstituted cyclohexadienone in which the gem nsubstituents are a perfluoroalkyl group and a trihydrocarnbylsiloxy group are prepared by perfluoroalkylating a nquinone with a perfluoroalkyltrihydrocarbylsilane in the npresence of an active catalyst under essentially anhydrous nconditions, preferably in a suitable liquid phase reaction nmedium, most preferably in a dipolar aprotic solvent. nThese gem-disubstituted compounds are readily convertible nto perfluoroalkyl-substituted aromatics and thus provide a nmeans of circumventing the traditional need for photo-nchlorination followed by halogen exchange in the preparantion of such products. |
