CAS 2071-20-7: Bis(diphenylphosphino)methane

Description: Bis(diphenylphosphino)methane, commonly referred to as DPPM, is a bidentate ligand widely used in coordination chemistry and catalysis. It features two diphenylphosphino groups attached to a central methane carbon, which allows it to effectively chelate metal ions. DPPM is characterized by its ability to stabilize various transition metals, enhancing their catalytic properties in reactions such as hydrogenation and cross-coupling. The compound is typically a white to off-white solid at room temperature and is soluble in organic solvents like dichloromethane and toluene. Its structure contributes to its steric and electronic properties, making it a valuable ligand in organometallic chemistry. DPPM can form stable complexes with metals such as palladium, platinum, and rhodium, facilitating a range of chemical transformations. Additionally, its phosphine groups can participate in various reactions, including oxidation and coordination with other ligands. Overall, bis(diphenylphosphino)methane is an important compound in synthetic chemistry, particularly in the development of efficient catalytic systems.
