A new biaryl monophosphine ligand enables a room-temperature Pd-catalyzed fluorination of various activated (hetero)aryl triflates and bromides with high regioselectivity. Analysis of the solid-state structures of several Pd(II) complexes, as well as density functional theory (DFT) calculations help to explain the enhanced reactivity.
