(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. The compound is used as a precursor to the 2-lithiated derivative of triphenylphosphine, which in turn is a precursor to other phosphine ligands.
The compound has been prepared by several methods. An efficient route is the coupling reaction of diphenylphosphine and 2-bromoiodobenzne, which is catalyzed by palladium complexes (Ph = C6H5):
Br(I) + HPPh2
N → Ph2
Br) + [Et3
The compound is isomorphous with (2-tolyl)diphenylphosphine.
