Oxepin is an oxygen -containing heterocycle consisting of a seven-membered ring with three double bonds. The parent C 6 H 6 O exists as an equilibrium mixture with benzene oxide. The oxepin–benzene oxide equilibrium is affected by the ring substituents. [1] . A related dimethyl derivative exists mainly as the oxepin isomer, an orange liquid. [2]

噁庚因 （英語： Oxepin），又称 噁庚英 、 氧杂 䓬 、 氧杂 环庚三烯，是完全 不饱和 的含氧七元 杂环化合物，化学式C 6 H 6 O。 它可以看作是一种 环辛四烯 的类似物，都具有八个π电子，虽然不符合 休克尔规则 的4n+2通式，但根据 分子轨道 的计算，预测可能有些 芳香性，在理论上有一定的意义。 [2] 可由4,5-二溴环己烯 环氧化物 在 碱 （如 DBU，Gillard et al. 或 甲醇钠）作用下发生 消除 制取： [3] 也可以用 呋喃 与 丁炔二酸二甲酯 发生 双烯加成 生成一个双环产物，光照 …
