Preparation and Reactivityof some New Keto- and Styrene-Based TrifluoromethoxylatedSynthons

We describe the preparation, by the means of an initial fluorodesulfurization reaction, of 2-trifluoromethoxy acetophenone as well as β-trifluoromethoxystyrenes derivatives. The synthesis and reactivity of these compounds are discussed in relation to the perturbation induced by the aliphatic trifluoromethoxy group.
