trans-1,2-Bis(diphenylphosphino)ethene

Description:
Trans-1,2-Bis(diphenylphosphino)ethene, with the CAS number 983-81-3, is a bidentate ligand commonly used in coordination chemistry and catalysis. This compound features a central ethene moiety with two diphenylphosphino groups attached to each carbon atom, resulting in a trans configuration that enhances its steric and electronic properties. The presence of phosphorus atoms allows for strong coordination with transition metals, making it valuable in various catalytic processes, including cross-coupling reactions and asymmetric synthesis. The diphenylphosphino groups contribute to the ligand's stability and solubility in organic solvents. Additionally, the compound exhibits interesting electronic characteristics due to the conjugation between the ethene and the phosphine groups, which can influence the reactivity of metal complexes formed with it. Overall, trans-1,2-Bis(diphenylphosphino)ethene is significant in the field of organometallic chemistry and is utilized in the development of advanced materials and pharmaceuticals.
