The silver trifluoroacetate-assisted reaction of alkyl halides with hydrogen peroxide has been investigated. Methyl 12-bromostearate furnished, for the first time, methyl 12-hydroperoxystearate in 34% yield. Methyl 12-bromo-oleate, however, gave cyclopropane hydroperoxides (via a homoallylic cation rearrangement) and hydroperoxy epidioxides (presumably via methyl 12-hydroperoxyoleate which could not
已经研究了三氟乙酸银与卤代烷与过氧化氢的辅助反应。12-溴硬脂酸甲酯首次以12%的产率提供了12-氢过氧硬脂酸甲酯。然而,12-溴-油酸甲酯产生了环丙烷氢过氧化物(通过均等阳离子重排)和氢过氧环氧乙烷(大概是通过12-氢过氧油酸甲酯无法分离)。在三氟乙酸银的存在下,通过使12-溴油酸甲酯与氢过氧化叔丁基反应,制得9,叔丁基过氧-10,11-亚甲基庚二酸甲酯。当三氟乙酸银被乙酸盐代替时,这些转化都没有发生。
