A study has been made of the electrochemistry of five unsymmetrically substituted diphenyliodonium salts at mercury cathodes in dimethylformamide containing tetramethylammonium perchlorate. Polarograms indicate that the iodonium cations undergo reduction in three stages:(1) one-electron reduction to yield either (a) iodobenzene and a substituted phenylmercury radical or (b) a substituted iodobenzene and a phenylmercury ...
