|Section2= }} Cyclobutanetetrone, also called tetraoxocyclobutane, is an organic compound with formula C4O4 or (-(C=O)-)4, the fourfold ketone of cyclobutane. It would be an oxide of carbon, indeed a tetramer of carbon monoxide. The compound seems to be thermodynamically unstable. As of 2000, it had yet to be synthesized in significant amounts but may have transient existence as detected by mass spectrometry. ==Related compounds== Cyclobutanetetrone can be viewed as the neutral counterpart of the squarate anion C4O42−, which is stable and has been known at least since 1959. The compound octahydroxycyclobutane or cyclobutane-1,1,2,2,3,3,4,4-octaol (-C(OH)2-)4 may be referred to in the literature as "hydrated tetraoxocyclobutane". 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「Cyclobutanetetrone」の詳細全文を読む スポンサード リンク
