Description

Application

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.
