Tricyclohexyl phosphine Usage And Synthesis

Chemical Properties	clear colorless to pale yellow solution

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. 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.
