Excited-State Palladium-Catalyzed Defluorinative Arylation of Polyfluoroarenes

Arnab Dey,   Cătălin Anghel,   Rajesh Kancherla  and  Magnus Rueping  

Abstract

Visible-light-induced excited-state palladium catalysis enables defluorinative C(sp2)-C(sp2) cross-coupling of polyfluoroarenes with aryl boronic acids under blue LED irradiation at room temperature. The Pd(OAc)2/BrettPhos catalyst selectively activates C(sp2)-F bonds without external photocatalysts, affording multifluorinated biaryls in good to excellent yields through photoinduced formation of Ar-Pd(II) intermediates.
