Cyclopropylidene compounds of type 1 are found to quench the fluorescence of 9,10-dicyanoanthracene (DCA). Nevertheless photo-oxygenation, in the presence of DCA, leads under no circumstances to dioxetanes but (in ethanol) to a methoxy hydroperoxide 5, as tentatively shown in Scheme 2. This hydroperoxide undergoes acid rearrangement either to a lactone or to a cyclobutanone, depending on the reaction
发现类型1的环亚丙基化合物可以猝灭9,10-二氰基蒽(DCA)的荧光。然而,如方案2所示,在DCA存在下,光氧合在任何情况下都不会导致二氧环乙烷,而是(在乙醇中)会导致甲氧基氢过氧化物5。氢过氧化物会发生酸重排,生成内酯或环丁酮,具体取决于在反应条件上(方案3)。
