Visible-light-induced trifluoromethylation of N-aryl acrylamides: a convenient and effective method to synthesize CF(3)-containing oxindoles bearing a quaternary carbon center.

Trifluoromethylation/arylation: N-aryl acrylamides undergo visible-light-induced tandem trifluoromethylation/arylation in the presence of a ruthenium photocatalyst with Togni's reagent as the CF3 source. This reaction serves as a powerful and ecofriendly synthetic method for the preparation of a variety of CF3 -containing oxindoles bearing a quaternary carbon center.
