Tricyclohexylphosphine

DescriptionTricyclohexyl phosphine is the tertiary phosphine with the formula P( C 6H11) 3. Commonly used as a ligand in organometallic chemistry, it is often abbreviated to PCy 3, where Cy stands for cyclohexyl. It is characterized by both high basicity (pK a = 9.7) and a large ligand cone angle (170°). Tricyclohexyl-phosphine is more basic (and so a better c-donor) than tribu tyiphosphine, which in turn is more basic than triphenyl phosphIne.

UsesTricyclohexyl Phosphine is a ligand catalyst used primarily in organometallic chemistry. Ligand used in the Pd-catalyzed coupling of malononitrile with aryl halides. suzuki reaction: 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. As a reagent, Tricyclohexylphosphine is used for a range of metal-catalyzed organic transformations. Crabtree's catalyst is an organoiridium compound containing tricyclohexyl phosphine used for hydrogenation of mono-, di-, tri-, and tetra- substituted substrates and hydrogen transfer reactions. Grubbs' catalysts consists of transition metal ruthenium and tricylohexyl phosphine utilized in olefin metathesis in synthetic organic chemistry.
