Beschreibung

Anwendung

This new aryl alkylphosphine ligand developed in Abby′s Doyle′s lab has been tailored specifically for nickel catalysis as demonstrated in the Suzuki coupling of acetals with boronic acids to generate benzylic ethers, reactions that pose challenges in Ni catalysis when using phosphine ligands developed for Pd-catalysed couplings.
