chemistry. This report describes the use of a substituted hydroquinone catalyst to promote radical perfluoroalkylation reactions. Mechanistic studies indicate that the reaction is initiated through formation of a visible light-absorbing halogen bonding complex between the hydroquinone catalyst and the perfluoroalkyl halide radical precursor.

A ligand-free, room temperature, Ni-catalyzed perfluoroalkylation of heteroarenes produced a diverse array of polyfluorinated adducts; potential in the late-stage functionalization of drugs and peptides is also demonstrated.
AbstractWe report the visible‐light‐induced trifluoromethylation of arenes and heteroarenes using sodium trifluoromethanesulfinate catalyzed by anthraquinone‐2‐carboxylic acid. This reaction is a metal‐free trifluoromethylation of arenes and heteroarenes catalyzed by a photoredox organocatalyst. Perfluoroalkylated arenes were also produced using sodium perfluoroalkylsulfinates.magnified image
