The Uses of 1,2-BIS(DIPHENYLPHOSPHINO)BENZENE
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.
