Organophosphorus compounds containing hydrolytically and metabolically stable C(sp3)– and C(sp2)–P bonds are widely used as reagents, ligands, pesticides, herbicides, flame retardants, surface modifiers, and antiviral and anticancer drugs. These applications rely on efficient C(sp3)– and C(sp2)–P bond-forming reactions. However, currently available C(sp2)–P cross-coupling protocols require high catalyst loadings
