Radical cations from methyl iodide CH/sub 3/I/sup .+/, and (CH/sub 3/I therefore ICH/sub 3/)/sup +/ are shown to be excellent oxidants with a one-electron redox potential presumably greater than or equal to +2 V. Absolute rate constants in the order of 10/sup 9/ M/sup -1/ have been determined for their reactions with various organic sulfides, disulfides, thiols, phenothiazines, and inorganic metal and halide ions. A similarly high reactivity has also been found for the hydroxyl radical adduct to methyl iodide, CH/sub 3/I(OH)/sup ./. The results are discussed in view of the electronic and steric structure of these oxidizing radical species and the substrates to be oxidized.
