1,2-Bis(diphenylphosphino)benzene (commonly abbreviated as dppbz)(CAT: M064316) is a bidentate phosphine ligand featuring two diphenylphosphino groups positioned ortho to each other on a benzene ring. This chelating ligand is widely used in organometallic chemistry and homogeneous catalysis, particularly for forming stable metal-ligand complexes with transition metals such as palladium, platinum, and rhodium. Its rigid backbone and close phosphorus donor spacing make it ideal for facilitating precise coordination geometries and promoting catalytic activity in cross-coupling, hydrogenation, and C–C bond formation reactions.
