Abstract A more reactive palladium catalyst than homogeneous Pd(PPh3)4 catalyst for the Heck reaction supported on a sulfur-terminated GaAs(001) plate was developed. Sulfur termination using (NH4)2Sx at 60 °C and Pd absorption in acetonitrile at 100 °C is essential for the preparation of an active and stable catalyst. The catalyst could be reused in this reaction up to ten times.
