Abstract

No need to get away: X-ray absorption spectroscopy of catalytically active palladium nanopartlcles during a SuzukiMlyaura cross-coupling reaction revealed that the nanopartlcles 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.
