Soluble in most organic solvents. Insoluble in water.


Tricyclohexylphosphine oxide is used as a ligand for a range of metal-catalyzed organic transformations. Ligand used in the Pd-catalyzed coupling of malononitrile with aryl halides.1 Bulky phosphine ligand used with a Pd(0)-triolefinic macrocycle catalyst for Suzuki coupling of aryl bromides and chlorides. This ligand is applied with Ni as a key intermediate in the formation of cylcopentane compounds.


Keep container tightly closed. Store away from oxidizing agents, stored indefinitely under an inert atmosphere in a tightly sealed container in a cool, dry location.
