The solvent-free, palladium-catalysed reaction of anilides with CuCl2 in the presence or absence of copper acetate yields ortho-chlorinated anilides in good to excellent yields, even on a large scale (100 mmol). By contrast, the equivalent reactions with copper bromide, either solvent free or in 1,2-dichloroethane, in the presence or absence of palladium, under air or inert conditions, gave the products
electrocatalysis strategy for the catalytic dehydrochlorination of DCE at the cathode simultaneously with anodic oxidative aromatic chlorination using the released HCl as the chloride source for the efficient synthesis of value‐added (hetero)arylchlorides. The mildness and practicality of the protocol was further demonstrated by the efficient late‐stage chlorination of bioactive molecules.
