| Tricyclohexyl phosphine Usage And Synthesis |
Description | Tricyclohexyl 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. | Chemical Properties | clear colorless to pale yellow solution | Uses | Tricyclohexylphosphine is used as a ligand in organometallic chemistry. As a reagent, it 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. | Uses |
- Tricyclohexyl 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.
