FeF 3 ‐Promoted Radical Fluoroalkylation of o‐Alkenylaryl Isocyanides to Access 2‐Fluoroalkylated Quinolines

An iron(III)‐promoted radical fluoroalkylation of o‐alkenylaryl isocyanides has been developed using readily available perfluoroalkyl iodides as fluoroalkyl source. This cyclization reaction features broad substrate scope and provides a simple and efficient approach for regioselective construction of biologically important 2‐fluoroalkylated quinolines in 38–81 % yields.
