The reactions of methylenecyclopropanes with diphenyl diselenide give ring-opened products in good yields at 150 [degree]C under nitrogen atmosphere for 3 h; the products can further undergo oxidative cyclization with hydrogen peroxide to furnish 3-phenylselenyl-2,5-dihydrofurans in moderate yields (three steps) at room temperature in CH(2)Cl(2) for 5 h; a plausible reaction mechanism has been proposed.
在氮气气氛下，亚甲基环丙烷与二苯基二硒醚在150℃反应3小时，可高产率得到开环产物；这些产物在室温下于二氯甲烷中用双氧水进一步进行氧化环化反应5小时，能以中等产率（三步反应）得到3-苯基硒基-2,5-二氢呋喃；并提出了一种合理的反应机理。
