|Section8= }} Wilkinson's catalyst is the common name for chlorotris(triphenylphosphine)rhodium(I), a coordination compound with the formula RhCl(PPh3)3 (Ph = phenyl). It is named after the chemist and Nobel Laureate, Sir Geoffrey Wilkinson who popularized its use. ==Structure and basic properties== The compound is a square planar, 16-electron complex. It is usually obtained in the form of a red-violet crystalline solid from the reaction of rhodium(III) chloride with excess triphenylphosphine.〔Bennett, M. A.; Longstaff, P. A. Complexes of Rhodium(I) with Triphenylphosphine. ''Chem. Ind. (London)'' 1965, p. 846.〕 The synthesis is conducted in refluxing ethanol which helps with the reduction.〔"Tris(triphenylphosphine)halorhodium(I)" J. A. Osborn, G. Wilkinson, Inorganic Syntheses, 1967, Volume 10, p. 67. 〕 Triphenylphosphine serves as the reducing agent yielding triphenylphosphine oxide. :RhCl3(H2O)3 + 4 PPh3 → RhCl(PPh3)3 + OPPh3 + 2 HCl + 2 H2O 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「Wilkinson's catalyst」の詳細全文を読む スポンサード リンク
