Abstract

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).
