Tris(acetonitrile)cyclopentadienylruthenium hexafluorophosphate is an organoruthenium compound with the formula ()PF6, abbreviated ()PF6. It is a yellow-brown solid that is soluble in polar organic solvents. The compound is a salt consisting of the hexafluorophosphate anion and the cation ()+. In coordination chemistry, it is used as a source of RuCp+ for further derivitization. In organic synthesis, it is a homogeneous catalyst. It enables C-C bond formation and promotes cycloadditions. The cyclopentadienyl ligand (Cp) is bonded in an η5 manner to the Ru(II) center. ==Preparation== The title complex is synthesized in two steps from the (benzene)ruthenium chloride dimer. In the first step, the Cp− group is installed using cyclopentadienylthallium:〔 :()2 + 2 TlCp + 2 NH4PF6 → 2 ()PF6 + 2 TiCl + 2 NH4Cl The second step entails photochemical displacement of the benzene ligand, which is replaced by three equivalents of acetonitrile (MeCN): :()PF6 + 3 MeCN → ()PF6 + C6H6 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「Tris(acetonitrile)cyclopentadienylruthenium hexafluorophosphate」の詳細全文を読む スポンサード リンク
