The transformation of hydroxyl group in benzyl or allyl alcohols to trifluoromethyl was achieved via the reaction of the corresponding alkyloxydiphenylphosphine and CuCF3, generated in situ from methyl fluorosulfonyldifluoroacetate and CuI, under mild conditions. A plausible mechanism was proposed on the basis of experimental results.

A novel and efficient free-radical-promoted copper-catalyzed decarboxylative alkylation of α,β-unsaturatedcarboxylicacids with ICH2CF3 and its analogues has been developed. This methodology provides a convenient access to the synthesis of allylic trifluoromethyl and β-CF3 ketone containing compounds as well as other biologically useful fluorinated molecules and materials.
A cobaloxime-catalyzed photochemical synthesis of allyl monofluorides from styrenes is described herein. This method is characterized by mild reaction conditions, low-cost catalyst, and broad substrate scope. Furthermore, this convenient method will provide a facilesynthesis toward novel monofluoroalkylated natural product and pharmaceutical derivatives. Mechanistic investigations indicate that a

this transformation typically requires four-step processes, specialty chemicals, and/or stoichiometric metals to access the trifluoromethyl-containing product. A two-step copper-catalyzed decarboxylative protocol for converting allylic alcohols to trifluoromethanes is reported. Preliminary mechanistic studies distinguish this reaction from previously reported Cu-mediated reactions.

A visible light induced palladium-catalyzed fluoroalkylation method was developed. The Heck-type alkyl coupling reaction enables the introduction of trifluoroethyl, difluoroethyl and other fluoroalkyl fragment into styrenes under mild reaction conditions without the use of additional photosensitizers and ensures access to fluoroalkylated olefins on a broad scale.
