Reaction of unsaturated fulvene endoperoxides with dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate gave saturated fulvene endoperoxides containing the 1,2-dihydropyridazine ring. Treatment of dihydropyridazine endoperoxides with water followed by phenyliodosyl bis(trifluoroacetate) oxidation provided acrylic acid derivatives and dimethyl pyridazine-3,6-dicarboxylate.
不饱和富烯内过氧化物与1,2,4,5-四嗪-3,6-二羧酸二甲酯的反应得到了含有1,2-二氢哒嗪环的饱和富烯内过氧化物。用水处理二氢哒嗪内过氧化物,然后氧化苯基碘基双(三氟乙酸酯),得到丙烯酸衍生物和3,6-二羧酸哒嗪二甲酯。
