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.

Triphenylphosphine oxide (1 mmol), dry n-hexane (1 mL) and complexed aluminum hydroxide reagent (1 mmol) were added to the Schlenk tube under nitrogen atmosphere and then the reaction was carried out with stirring at room temperature for 10 minutes. The completion of the reaction mixture was monitored by TLC spot plate and at the end of the reaction, the reaction mixture was filtered through silica gel and the reaction mixture was washed several times with ethyl acetate, the residue obtained from the evaporation of ethyl acetate was separated and purified by silica gel column chromatography using pure cyclohexane to obtain the tricyclohexylphosphine product.
