Highly reactive organopalladium catalysts have been successfully developed on a sulfur-terminated (S-terminated) GaAs(001) substrate, which has a highly uniform ($2 \times 6$) reconstructed surface formed by molecular-beam epitaxy. This new material catalyzed the coupling reaction of iodobenzene and methyl acrylate and could be used repeatedly at least ten times to give good to excellent yields in the Heck reaction. The immobilization of organopalladium in acetonitrile at 100 °C followed by treatment at elevated temperature in acetonitrile is essential for producing an active and stable catalyst on S-terminated GaAs(001). Moreover, we have shown that the amount of S–Ga bonds is responsible for stabilizing the activity of the catalyst. In addition, we examined the physical character of organopalladium on a surface before and after the Heck reaction by X-ray photoelectron spectroscopy (XPS).
