Cu-Mediated Synthesis of Indolines and Dihydroisoquinolinones through Arylperfluoroalkylation of Unactivated Alkenes

The copper-mediated fluroalkylation/cyclization of N-allyl anilines has been described using fluoroalkyl iodides as fluoroalkylation reagents for the first time. The reaction provides an efficient and direct access to 3-fluoroalkyl indolines in moderate to good yields with unactivated double bonds as the radical acceptor. This protocol combines a simple experimental procedure with low-costing fluoroalkylated sources and excellent functional group tolerance.
