|Section2= }} Benzotriyne or cyclo()carbon is a hypothetical chemical compound, an allotrope of carbon with molecular formula C6. The molecule is a ring of six carbon atoms, connected either by alternating triple and single bonds or by double bonds. It is, therefore, a potential member of the cyclo()carbon family. There have been a few attempts to synthesize benzotriyne, e.g. by pyrolysis of mellitic anhydride, but without success (as of 2011). Recent investigations have concluded that benzotriyne is unlikely to exist due to the large angle strain. A likely alternative would be a cyclical cumulene called cyclohexahexaene, which should itself be a metastable species. == References == 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「benzotriyne」の詳細全文を読む スポンサード リンク
