Abstract
Aromatic cation radicals, produced by oxidation of benzene and toluene with peroxydisulphate ion in water–acetonitrile mixtures, are efficiently trapped by copper(II) chloride with formation of moderate to good yields of ring chlorinated products; in contrast, side chain chlorination of toluene occurs when copper(II) chloride is replaced by chloride ion.Keywords
