对二氧杂环己烷四酮(系统命名为1,4-二氧杂-2,3,5,6-环己烷四酮)是一种有机化合物,化学式为C4O6。它是一种碳的氧化物,可以被看做二氧杂环己烷含有四个酮基的衍生物。它也可以被看作两分子乙二酸形成的环状酸酐,或是其内酸酐乙二酸酐(一种假想的酸酐,化学式C2O3)的二聚体

1998年,Paolo Strazzolini和其他人通过乙二酰氯(COCl)2乙二酰溴(COBr)2乙二酸银于乙醚中在-15 °C反应制得了该物质,然后在低温低压蒸发溶剂即可。这种可以溶解于−30°C的乙醚或三氯甲烷中并稳定存在,但加热到0°C时分解为一氧化碳二氧化碳的1:1混合物。[1]这种物质的稳定性与结构也可以用理论方法进行分析。[2]
