| Questions And Answer | Back Directory | [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. |
