Defying the oxidative-addition prerequisite in cross-coupling through artful single-atom catalysts

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: April 4, 2025

Heterogeneous single-atom catalysts (SACs) have gained significant attention for their maximized atom utilization and well-defined active sites, but they often struggle with multi-stage organic cross-coupling reactions due to limited coordination space reactivity. Here, we report an "anchoring-borrowing" strategy combined facet engineering develop artful (ASACs) through anchoring foreign single atoms onto specific facets of the non-innocent reducible carriers. ASACs exhibit adaptive coordination, effectively bypassing oxidative-addition prerequisite bivalent elevation at a metal site in both homogenous heterogeneous cross-couplings. For example, Pd1-CeO2(110) ASAC exhibits unparalleled activity coupling more accessible aryl chlorides, challenging heterocycles, outperforming traditional remarkable turnover number 45,327,037. Mechanistic studies reveal that leverage dynamic structural changes, carriers acting as electron reservoirs, significantly lowering reaction barriers. Furthermore, enable efficient synthesis biologically compounds, drug intermediates, pharmaceutical ingredients (APIs) scalable high-speed circulated flow synthesis, underscoring great potential sustainable fine chemical manufacturing.
