A practical method for electrochemical iodination of aromatic compounds was developed. The method involves the generation of I+ by electrochemical oxidation of I2 in CH3CN using H2SO4 as supporting electrolyte followed by the reaction with aromatic compounds. The para/ortho selectivity for the reaction of monosubstituted benzenes was significantly improved using dimethoxyethane as cosolvent in the second step. The reaction with ...
