Efficient electrocatalysis for the preparation of (hetero)aryl chlorides and vinyl chloride with 1,2‐dichloroethane

Although the application of DCE as a chlorinating reagent in organic synthesis concomitant with release of vinyl chloride as a useful byproduct is a fantastic idea, it is still a big challenge and is hardly achieved because of the harsh dehydrochlorination conditions and the inert C‐H chlorination process. Here we report a bifunctional electrocatalysis strategy for catalytic dehydrochlorination of DCE at cathode simultaneously with the anodic oxidative aromatic chlorination using the released HCl as chloro‐source for the efficient synthesis of value‐added (hetero)aryl chlorides. The mildness and practicality of the protocol was further demonstrated by the efficient late stage chlorination of bioactive molecules.
