Chemical Properties

white to light yellow crystal powde

Uses

1,2-Bis(diphenylphosphino)benzene (DPPB) can be used:

• As a chelating ligand in the synthesis of luminescent copper(I) halide complexes.
• In the synthesis of copper-1,2-bis(diphenylphosphino)benzene catalyst which is used for the β-boration of α, β-unsaturated amide.
• As an alternative to TMEDA for the selective cleavage of sp³ C-X bond in fluoroaromatic coupling reactions catalyzed by iron.
• As a ligand in the synthesis of alkenylboronates from acetylenic esters.
• To synthesize copper-diphosphine complexes which are used as homogeneous catalysts for N-formylation of a wide range of amines.

Application

1,2-Bis(diphenylphosphino)benzene is a highly efficient bidentate phosphine ligand. It forms a stable five-membered ring chelate with a single transition metal atom (such as palladium, nickel, rhodium, gold, etc.) through its two adjacent diphenylphosphine groups. This structure gives the catalyst high activity and high stability, so it is widely used in various homogeneous catalytic reactions.
