Palladium-Catalyzed Regioselective Allylic Alkylation of 1-Aryl-2,3,3-trifluoroallyl Acetates

The palladium-catalyzed allylic alkylation of 1-aryl-2,3,3-trifluoroallyl acetates, which possess fluorinated olefinic parts, has been demonstrated; the reaction was effectively conducted by using P(t-Bu) 3 or XANTPHOS as a ligand, and the reaction proceeded with a high regioselectivity.
