This yellow, air-stable solid is a precursor to a variety of other rhenium complexes. In this diamagnetic compound, Re has an octahedral coordination environment with one oxo, three chloro and two mutually trans triphenylphosphine ligands. The oxidation state of rhenium is +5 and its configuration is d2. ==Synthesis== ReOCl3(PPh3)2 is commercially available, but it is readily synthesized by reaction of perrhenic acid with triphenylphosphine in a mixture of hydrochloric acid and acetic acid. In this reaction, Re(VII) is reduced to Re(V), and triphenylphosphine is oxidized to its oxide. : HReO4 + 3 HCl + 3 PPh3 → ReOCl3(PPh3)2 + Ph3PO + 2 H2O The required perrhenic acid solution can be prepared in situ from rhenium(VII) oxide. 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「Oxotrichlorobis(triphenylphosphine)rhenium(V)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
