P‐pyrrole phosphines (R2Ppyr), in which a pyrrole group is directly bonded to the phosphorus atom, act as monodentate k‐P ligands towards gold(I) center to afford either neutral or cationic mononuclear complexes as well as neutral dinuclear complexes. All of these new gold(I) complexes have been structurally characterized and their first uses in catalysis have demonstrated their effectiveness as precatalysts
