摘要：

The mechanism of the bipyridylium comproportionation reaction has been determined using the redox states of methyl viologen (MV). The reaction, hitherto presumed to follow the stoichiometry MV2+ + MV0 --> 2 MV+, has been investigated using in situ electrochemical EPR and UV-VIS spectroscopy and been shown to proceed via an intermediate step forming a spin-paired radical cation dimer (MV)2(2+). Dimer dissociation occurs as a subsequent reaction stage.
