Applications
-
Homogeneous Catalysis:
-
Used as a ligand in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck reactions).
-
Coordinates with rhodium or ruthenium in hydrogenation and hydroformylation reactions.
-
-
Materials Chemistry:
-
Serves as an auxiliary ligand in synthesizing metal-organic frameworks (MOFs) or functionalized polymers.
-
-
Asymmetric Synthesis:
-
Can be modified (e.g., chiral derivatization at phosphorus or phenyl groups) for asymmetric catalysis.
-
Handling & Safety
-
Store under inert gas, protected from light, and at low temperatures (2–8°C).
-
Organophosphorus compounds may be toxic—handle with gloves/safety goggles.
