A solution of RuCl 3 in concentrated hydrochloric acid is capable of chlorinating aromatic compounds catalytically, if O 2 is present as the oxidizing agent (brominations can be achieved in hydrobromic acid). When olefins are chosen as substrates, two Cl atoms are added to the double bond in an anti fashion, while hydrochlorination products are formed simultaneously. According to the products observed in both types of reactions for various substrates in this 3‐phase system, the halogenations proceed via electrophilic pathways.
