Metal-free electrohalogenation of olefins with aqueous NaX mediators

Abstract

We are the first to apply traditional inorganic chloralkali industrial chemistry to the halogenation of organic olefins. This environmentally benign protocol employs low-cost, recyclable graphite felt as the electrode and utilizes aqueous NaCl and NaBr solutions as both halogen sources and supporting electrolytes. It exhibits broad substrate scope, operational simplicity, and scalability to the kilogram level, making it highly attractive for industrial implementation.
