Abstract
A solution of RuCl3 in concentrated hydrochloric acid is capable of chlorin ating 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. Accord ing to the products observed in both types of reactions for various substra tes in this 3-phase system, the halogenations proceed via electrophilic pat hways.
