Cas no 137349-65-6 (Bis(dicyclohexylphosphino)methane)

Bis(dicyclohexylphosphino)methane (dcpm) is a bidentate phosphine ligand widely used in coordination chemistry and homogeneous catalysis. Its rigid dicyclohexyl backbone enhances steric bulk, promoting stability in metal-ligand complexes while maintaining electron-donating properties. The ligand's chelating ability, facilitated by the methylene bridge, improves catalytic efficiency in cross-coupling, hydrogenation, and hydroformylation reactions. Its air-stable nature and compatibility with late transition metals (e.g., Pd, Pt, Rh) make it a versatile choice for organometallic synthesis. The ligand's robust structure also minimizes decomposition under harsh conditions, ensuring consistent performance in industrial and academic applications.
