alkenes with MgCl2 as the chlorine source. This method provides operationally simple, sustainable, and efficient access to a variety of vicinally dichlorinated compounds. In particular, alkenes with oxidatively labile functional groups, such as alcohols, aldehydes, sulfides, and amines, were transformed into the desired vicinal dichlorides with high chemoselectivity. Mechanistic data are consistent with
我们报告了以 MgCl2 作为氯源对烯烃进行 Mn 催化的电化学二氯化。该方法提供了操作简单、可持续且有效的方法,可获取多种邻位二氯化合物。特别是,具有氧化不稳定官能团的烯烃,如醇、醛、硫化物和胺,以高化学选择性转化为所需的邻位二氯化物。机理数据与金属介导的 Cl 原子转移一致,作为实现双 C-Cl 键形成的主要途径,并与涉及氯气电化学演化和 Cl2 介导的亲电二氯化的替代途径相矛盾。
