Trifluoromethylation of carbonyl compounds

A process which comprises reacting under substantially anhydrous conditions a perfluoroalkyltrihydrocarbylsilane and a carbonyl compound in the presence of a catalyst such that the carbonyl compound is perfluoroalkylated.

Gem-disubstituted cyclohexadienones and their production

Quinones may be perfluoroalkylated by means of perfluoroalkyltrihydrocarbyl silane using certain active alkali metal salt catalysts devoid of fluorine (e.g., LiN3, NaN3, KN3, NaCN KCN, CsCN, NaOH, KOH, K2 CO3, and Cs2 CO3). 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.
