(2-Bromophenyl)diphenylphosphine is primarily used as a ligand in coordination chemistry and catalysis. It plays a significant role in forming metal complexes, particularly with transition metals like palladium, platinum, and nickel, which are essential for various cross-coupling reactions. These reactions are widely applied in organic synthesis to create complex molecules, including pharmaceuticals, agrochemicals, and advanced materials. Its unique structure, combining a bromophenyl group with diphenylphosphine, enhances its ability to stabilize metal centers and modulate reactivity, making it valuable in asymmetric synthesis and fine chemical production. Additionally, it is employed in the development of organometallic compounds for research and industrial applications.
