Oxatriquinacene is an organic cation with formula . It is an oxonium ion, with a trivalent oxygen atom with +1 charge connected to carbons 1,4, and 7 of a cyclononatriene ring, forming three fused pentagonal cycles. Oxatriquinacene has remarkable stability compared to other oxonium cations, although not as extreme as that of the similar oxatriquinane. It reacts with water, but can be dissolved in acetonitrile. It is of interest as a possible precursor to oxaacepentalene, a hypothetical neutral aromatic species.〔 Oxatriquinacene was obtained in 2008 by Mascal and others, through a variant of the synthesis that led them to oxatriquinane.〔 〕〔 〕〔 〕 ==See also== * Triethyloxonium tetrafluoroborate * Brookhart's acid * Pyrylium salt 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「oxatriquinacene」の詳細全文を読む スポンサード リンク
