This highly reactive, hygroscopic brown solid is used to synthesize organofluorine compounds.〔Coe, P. L. "Cobalt(III) Fluoride" in Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. .〕 CoF3 is a powerful fluorinating agent that leaves CoF2 as the byproduct. ==Preparation== CoF3 is prepared in the laboratory by treating CoCl2 with fluorine at 250 °C:〔Priest, H. F. "Anhydrous Metal Fluorides" Inorganic Syntheses McGraw-Hill: New York, 1950; Vol. 3, pages 171-183. 〕 :CoCl2 + 3/2 F2 → CoF3 + Cl2 This conversion is a redox reaction: Co2+ and Cl− are oxidized to Co3+ and Cl2, respectively, while F2 is reduced to F−. Cobalt(II) oxide (CoO) and cobalt(II) fluoride (CoF2) can also be converted to cobalt(III) fluoride using fluorine. 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「Cobalt(III) fluoride」の詳細全文を読む スポンサード リンク
