(2-Bromophenyl)diphenylphosphine is an organophosphorus compound with the formula (C6H4Br)P(C6H5)2.

It is a white crystalline solid that is soluble in nonpolar organic solvents.

[1] An efficient route is the coupling reaction of diphenylphosphine and 2-bromoiodobenzene, which is catalyzed by palladium complexes (Ph = C6H5):[2] The compound is isomorphous with (2-tolyl)diphenylphosphine.

[3] Lithiation with butyl lithium gives o-lithiated triphenylphosphine.

The bromide also forms a Grignard reagent.
