A short and efficient synthesis of a heterogeneous palladium catalyst supported on a rasta resin bearing diphenylphosphanyl ligands is reported. This catalyst was used successfully for Suzuki–Miyaura reactions of aryl bromides in the presence of only 0.25 milli‐equiv. of supported palladium. The catalyst was reused several times with no loss of efficiency, and the amount of palladium leached in the reaction medium is extremely low (< 1 % of the initial amount).
