A newly developed, environmentally benign palladium catalyst supported on gallium arsenide, {Pd}‐S‐GaAs(001), has both the lowest recorded leaching and high recyclability for Suzuki–Miyaura coupling. Measurements of the catalyst surface by synchrotron radiation X‐ray photoelectron spectroscopy show a relationship between the surface and the activity of the catalyst. Since {Pd}‐S‐GaAs(001) makes efficient use of the rare metal Pd, it is a useful palladium catalyst from an atom‐ economical perspective. Two heterogeneity tests clarify that the presence of immobilized palladium on SGaAs is important for higher catalytic activity.
