while in benzene it afforded various side-chain-brominated compounds. Shifts of bromine atom catalyzed by succinimide were observed in benzene, presumably via intermolecular radical pathways. Using these reactions, various side-chain-functionalyzed derivatives of 1, including epoxy compounds, were prepared.
在己烷中用 NBS 处理愈创甘油醚 (1) 只得到 3-溴化合物,而在苯中它提供各种侧链溴化化合物。在苯中观察到由琥珀酰亚胺催化的溴原子的位移,可能是通过分子间自由基途径。使用这些反应,制备了 1 的各种侧链官能化衍生物,包括环氧化合物。
