A heteroaryl phosphine ligand widely used in organometallic chemistry and homogeneous catalysis. Commonly employed as a ligand for palladium, platinum, rhodium, ruthenium, iridium, nickel and copper catalysts in cross-coupling reactions, hydrogenation, carbonylation, C–N/C–C bond formation, and pharmaceutical intermediate synthesis. Also used as a building block for functional phosphine ligands and coordination complexes.
