The carbonyl oxide (1), derived from the 2,3,7-trioxabicyclo[2.2.1]heptene (3) by thermal rearrangement, yields, as major products, methyl 1,2-dioxolane-4-carboxylate (8) and the novel tricyclic biperoxide (4)(whose structure was established by X-ray diffraction), by reaction with methyl acrylate and the acrylate (3) respectively, whereas it yields 5-ethoxy-1,2-dioxolane (9) with ethyl vinyl ether
通过热重排衍生自2,3,7-三恶双环[2.2.1]庚烯(3)的羰基氧化物(1)作为主要产物产生1,2-二氧戊环-4-羧酸甲酯(8)和新型三环双过氧化物(4)(通过X射线衍射确定其结构),分别与丙烯酸甲酯和丙烯酸酯(3)反应,而生成带有乙基乙烯基的5-乙氧基-1,2-二氧戊环(9)醚。
