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.

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
