involves alkoxyl radicals generated from N‐alkoxypyridinium salts. A wide range of alkenes are smoothly difunctionalized in an anti‐Markovnikov fashion, affording various functionalized alkyl alkyl ethers. Notably, this mild process tolerates a number of functional groups and is efficiently carried out under both batch and flow conditions. Importantly, electron paramagnetic resonance (EPR) experiments
本文报道的是一种新型的光氧化还原催化的醚合成方法,它涉及由N-烷氧基吡啶鎓盐生成的烷氧基自由基。各种各样的烯烃以反马尔可夫尼可夫的方式平稳地进行双官能化,从而提供了各种官能化的烷基烷基醚。值得注意的是,这种温和的方法可以耐受许多官能团,并且可以在间歇和流动条件下有效地进行。重要的是,通过自旋俘获进行了电子顺磁共振(EPR)实验,以表征参与该自由基/阳离子过程的自由基中间体。
