✦ Synopsis

A recent communication by Parker et al. 1 claimed to demonstrate that tetra-panisylethylene (TAE) was oxidized in acetonitrile (CHa CN) in a direct two-electron transfer. However, our recent work on the electrochemical oxidation of substituted ethylenes in CH3 CN and methylene chloride (CH2 C12), as well as past electron spin resonance (e.s.r.) studies 2 , have demonstrated that TAE is oxidized in two closely spaced, one-electron steps; other substances, such as tetrakis(p-N,N-dimethylaminophenyl)ethylene (TMPE), experimentally show behavior consistent with a direct two-electron transfer. The following discussion contrasts the behavior of TAE and TMPE; a full description of the electrochemical behavior of these and related compounds will be given elsewhere.
