Application Role:

Ligand in homogeneous catalysis and an intermediate for synthesizing other organophosphorus compounds.

 

Uses

1. Ligand in Catalysis: Dicyclohexylphosphine is used as a ligand in transition metal-catalyzed reactions, including hydrogenation, hydroformylation, and cross-coupling reactions.
2. Synthesis of Complex Ligands: Serves as a key precursor for synthesizing larger, structured phosphine ligands (e.g., 2-Dicyclohexylphosphino-2',4',6'-triisopropylbiphenyl).
3. Synthesis Intermediate: Used to prepare other valuable phosphine derivatives, such as dicyclohexylphosphine oxide.

Typical Usage & HandlingUsage: Added in catalytic amounts (typically 0.5-5 mol% relative to the metal catalyst) as a ligand.

Handling:

Highly sensitive to air and moisture. Must be handled and stored under an inert atmosphere (e.g., nitrogen or argon).

Storage: Keep tightly sealed under inert gas at 2-8°C.

Note: For research use only. Not for human or veterinary use.
