one-electron oxidant, producing radical cations from olefins and promoting the efficient radical cation [2 + 2] and [2 + 4] cycloaddition reactions. Subsequent chain propagation afforded trisubstituted cyclobutane or cyclohexene derivatives, and this facile route enables the replacement of rare metals with sustainable, green, and inexpensive iron in radical cation cycloadditions.
铁(III)-聚吡啶基配合物及其衍生物显示出足够的氧化潜能,可作为单电子氧化剂,由烯烃产生自由基阳离子,并促进有效的自由基阳离子[2 + 2]和[2 + 4]环加成反应。随后的链增长提供了三取代的环丁烷或环己烯衍生物,这种简便的途径使得能够在自由基阳离子环加成中用可持续,绿色和廉价的铁替代稀有金属。
