An aerobic oxidative cross-coupling reaction of alkenes with polyfluorobenzenes, through palladium-catalyzed allylic C-H activation, is reported. This attractive route provides a new way to forge allylic C-C bonds of valuable products, in good yields, with high regioselectivity.

copper‐ and phosphine‐ligand‐free Pd‐catalyzed directallylation of electron‐deficient polyfluoroarenes with allylicchlorides and the reaction mechanism are described (see scheme). The simple catalytic system, broad substrate scope, and excellent functional‐group compatibility of this protocol provides a useful and facile access to allylated polyfluoroarenes.
