Synthesis of Aryliodides from Diazonium Tetrafluoroborate in Dimethylsulfoxide

Abstract
One of the best methods for the introduction of iodine in the aromatic ring, is the reaction of arenediazonium salts with iodine ions in water1, for which a free radical mechanism was proposed2. Although the yields are generally good, numerous attempts were made to improve the method and to simplify the isolation procedure.
