|Section2= |Section3= }} Tricyclohexylphosphine is the tertiary phosphine with the formula P(C6H11)3. Commonly used as a ligand in organometallic chemistry, it is often abbreviated to PCy3, where Cy stands for cyclohexyl. It is characterized by both high basicity (pKa = 9.7)〔C. A. Streuli, "Determination of Basicity of Substituted Phosphines by Nonaqueous Titrimetry", Analytical Chemistry 1960, volume 32, pages 985-987.〕 and a large ligand cone angle (170°). Important complexes containing P(Cy)3 ligands include the 2005 Nobel Prize-winning Grubbs' catalyst and the homogeneous hydrogenation catalyst Crabtree's catalyst. ==References== 〔 Image:Grubbs_Catalyst_1st_Generation.svg|Grubbs catalyst (1st generation) Image:Crabtree.png|Crabtree's catalyst 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tricyclohexylphosphine」の詳細全文を読む スポンサード リンク
