1,4-Bis(diphenylphosphino)butane (dppb) is an organophosphorus compound with the formula (Ph2PCH2CH2)2. It is less commonly used in coordination chemistry than other diphosphine ligands such as dppe. It is a white solid that is soluble in organic solvents.
Nickel complexes in which the ligand is bidentate [1] [2] or monodentate [3] are known. Palladium complexes containing dppb are used in a variety of catalytic reactions. [4] [5] The ligand's natural bite angle is 94° in its bidentate coordination mode. [6]
