General description

We are committed to providing greener alternatives that adhere to the 12 Principles of Green Chemistry. This chiral ligand provides a chiral ligand framework for metal-catalyzed asymmetric transformations, enabling high stereoselectivity while reducing stereoisomeric waste, thus aligns with Green Chemistry principle "Catalysis". Click here for more information.

Application

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.
