Arene-chlorination using chlorinated waste

Herein described is a method for chlorination of a substrate compound containing an aromatic moiety, in particular an arene moiety with 3 to 20 carbon atoms, wherein the substrate compound is reacted with a chlorine-donor, in particular an organic chlorine donor, in the presence of a catalyst, an oxidising agent, and a solvent. Also described is the use of a chlorine-containing compound, in particular a chlorine-containing solid or liquid organic compound, more particularly a chlorinated organic waste compound, as chlorine-donor for the chlorination of a substrate compound containing an aromatic moiety, in particular an arene moiety, with 3 to 20 carbon atoms.
