1,2-Bis(diphenylphosphino)benzene (dppbz) is an organophosphorus compound with the formula C₆H₄(PPh₂)₂ (Ph = C₆H₅). Classified as a diphosphine ligand, it is a common bidentate ligand in coordination chemistry.^[1] It is a white, air-stable solid. ^[2] As a chelating ligand, dppbz is very similar to 1,2-bis(diphenylphosphino)ethylene.
