2-trifluoro-1-ethanone with benzylic Grignard reagents affords by 1,2-addition unsaturatedallylic alcohols. These alcohols readily undergo dehydration and cyclisation to give trifluoromethylnaphthalenes. The generality of this procedure was established by reaction with diverse benzyl and allyl Grignard reagents and by reaction of a number of unsaturated ketones. The resulting trifluoromethylnaphthalenes were oxidised
