electron transfer (SET) process occurs between these two reactants by forming an electron-donor acceptor complex. Not only does this unusual single electron transfer reaction between an alkene and NIS add fundamentally important knowledge to organic chemistry, it also provides a valuable synthetic method as the new SET reaction mode with opposite regioselectivity as compared with the traditional ionic mode
烯烃与亲电子试剂的亲电加成已在有机合成中得到广泛研究和应用。有机化学教科书将烯烃和碘亲电试剂(例如元素碘和N-碘代琥珀酰亚胺(NIS))之间的经典反应描述为典型的离子反应,其中形成碘鎓离子,然后受到亲核试剂的攻击。然而,在本文中,我们报告了烯烃和 NIS 之间一种新的、不寻常的反应模式;也就是说,通过形成电子供体受体复合物,在这两种反应物之间发生单电子转移(SET)过程。烯烃和NIS之间这种不寻常的单电子转移反应不仅为有机化学增添了极其重要的知识,而且还提供了一种有价值的合成方法,作为与传统离子模式相比具有相反区域选择性的新SET反应模式。
