Abstract
Treatment of p-alkylbenzenesulfonic acids with mCPBA and molecular iodine gave p- alkyliodobenzenes in good to moderate yields via electrophilic ipso-substitution by the iodonium species (I+) formed. This desulfonyloxyiodination was promoted by the addition of a catalytic amount of iodoarenes, such as o-iodobenzoic acid. The same treatment of dimethylbenzenesulfonic acids and trimethylbenzenesulfonic acids with mCPBA and ...
