No need to get away : X‐ray absorption spectroscopy of catalytically active palladium nanoparticles during a Suzuki–Miyaura cross‐coupling reaction revealed that the nanoparticles were stable under the reaction conditions, and that cross‐coupling involved the direct participation of surface palladium defect sites in the catalytic cycle (see picture). Selective chemical and structural poisons provided further evidence for a heterogeneous active site.
