A palladium-catalyzed intramolecular oxidative aryltrifluoromethylation reaction of activated alkenes has been explored. The reaction allows for an efficient synthesis of a variety of CF(3)-containing oxindoles. Preliminary mechanistic study indicated that the reaction involves a C(sp(3))-Pd(IV)(CF(3)) intermediate, which undergoes reductive elimination to afford a C(sp(3))-CF(3) bond.
