1,2-Bis(diphenylphosphino)ethane

CAS 1663-45-2: 1,2-Bis(diphenylphosphino)ethane

Description:1,2-Bis(diphenylphosphino)ethane, commonly referred to as DPPE, is a bidentate ligand widely used in coordination chemistry and catalysis. It features two diphenylphosphino groups attached to a central ethane backbone, which allows it to effectively chelate metal ions. DPPE is characterized by its ability to stabilize various transition metals, enhancing their reactivity in catalytic processes, particularly in hydrogenation and cross-coupling reactions. The compound is typically a white to off-white solid at room temperature and is soluble in organic solvents such as dichloromethane and toluene. Its structure contributes to its steric and electronic properties, making it a valuable ligand in the synthesis of metal complexes. Additionally, DPPE can exhibit different coordination modes depending on the metal center, influencing the overall geometry and reactivity of the resulting complexes. Safety precautions should be taken when handling DPPE, as it may pose health risks if ingested or inhaled.
