Ligands for metals and improved metal-catalyzed processes based thereon

One aspect of the present invention relates to ligands for transition metals. A second aspect of the present invention relates to the use of catalysts comprising these ligands in transition metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject methods provide improvements in many features of the transition metal-catalyzed reactions, including the range of suitable substrates, reaction conditions, and efficiency.

Use of polymer-supported dialkylphosphinobiphenyl ligands for palladium-catalyzed amination and Suzuki reactions

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 mixtures 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.
