The preparations of polymer-supported dialkylphosphinobiphenyl ligands (3) are reported. A palladium catalyst based on ligand 3a is active for amination and Suzuki reactions using unactivated aryl iodides, bromides, or chlorides. Filtration of the catalyst from the reaction mixture allows for simplified product isolation via an aqueous workup. The resin-bound catalyst can be recycled without additional palladium in both the amination and Suzuki reactions.
