By decomposition of alkyl hydroperoxides 1-8 with ferrous sulfate-cupric acetate reagent, intramolecular functionalisation of remote non-activated C atom takes place and unsaturated alcohols with double bond mainly at δ-position are obtained. The reaction proceeds involving the corresponding alkoxy radical 9 and δ-carbon radical 10 as intermediates. One-electron oxidative interception of δ-carbon radical
通过用硫酸亚铁-乙酸亚铜试剂分解氢过氧化物烷基1-8,进行远程未活化C原子的分子内官能化,并获得主要在δ位具有双键的不饱和醇。反应进行,其中包含相应的烷氧基自由基9和δ-碳自由基10作为中间体。乙酸铜单电子氧化δ-碳自由基不涉及相应的碳离子;取而代之的是,形成烷基铜中间体11,并通过消除得到烯烃醇。发现该消除过程的同位素效应为k h / k d = 6.1。
