The e.s.r. spectra derived from 7-bromo-5,6-epoxyheptene derivatives such as epoxygeranyl bromide (7) showed that the main free radical intermediates were tetrahydrofuranylmethyl radicals (11), formed by ring opening of the epoxide and subsequent exocyclisation of the unsaturated alkoxyl radicals. The 7-oxabicyclo[2.2.1]heptanyl methyl radicals (12) were also formed via a double cyclisation. Products
由7-溴5,6-环氧庚烯衍生物(例如环氧香叶基溴化物(7))衍生的esr光谱表明,主要的自由基中间体为四氢呋喃基甲基(11),由环氧化物开环并随后将不饱和烷氧基外环化而成部首。7-氧杂双环[2.2.1]庚基甲基(12)也通过双环化形成。从(7)与氢化三正丁基锡的反应中分离出衍生自这两种中间体的产物。
