通过苄基氧化反应合成了氧代苏满烯。电子和氧化还原性质被揭示，表现出扩大的π共轭相比，苏曼烯。单晶X-射线分析表明，monooxsumanene柱状π堆积在一个凹凸的方式。三氧代衍生物的立体选择性三甲基化是通过1，2-加成羰基进行的。
Oxosumanenes were synthesized through benzylic oxidation. The electronic and redox properties were revealed to exhibit the expanded pi-conjugation compared to sumanene. Single-crystal X-ray analysis of monooxosumanene showed columnar pi-stacking in a concave-convex fashion. Stereoselective trimethylation of the trioxo derivative was performed via 1,2-addition to the carbonyl groups.
