It is a colorless solid, used as a strong acid. The compound was first reported by Volpe, Grant, and Brookhart in 1992. ==Preparation== This compound is prepared by treatment of NaBAr’4 in diethyl ether (Et2O) with hydrogen chloride: : NaBAr'4 + HCl + 2 Et2O → ()+BAr'4− + NaCl NaBAr’4 is soluble in diethyl ether, whereas sodium chloride is not. Precipitation of sodium chloride thus drives the formation of the oxonium acid compound, which is isolable as a solid.〔 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「Brookhart's acid」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.
