Synthesis and Reactivity of a Mono-σ-Aryl Palladium(IV) Fluoride Complex

Abstract
This communication describes the rational design and synthesis of the remarkably stable PdIV monoaryl fluoride complex (t-Bu-bpy)PdIV(p-FC6H4)(F)2(FHF) (t-Bu-bpy = 4,4′-di-tert-butyl-2,2′-bipyridine). This and related complexes undergo Ar−F bond formation in the presence of “F+” sources. This work serves as a foundation for the development of PdII/IV-catalyzed coupling reactions to form aryl fluorides.
