bond formation to an aryl ring is reported. The reactions are conducted under mild conditions and afford tetralin derivatives bearing difluoromethyl as well as other fluoroalkyl groups in good to high yields. In addition, the study indicates that 6-exo radical cyclization of an alkyl radical to a phenyl ring is faster than the respective 5-exo radical cyclization. A computational study provides insights

An efficient method for photocatalytic perfluoroalkylation of vinyl‐substituted all‐carbon quaternary centers involving 1,2‐aryl migration has been developed. The rearrangement reactions use fac‐Ir(ppy)3, visible light and commercially available fluoroalkyl halides and can generate valuable multisubstituted perfluoroalkylated compounds in a single step that would be challenging to prepare by other methods
