摘要

The unusual 7π electron structure of certain five-membered rings has allowed the construction of a unique, reversible one-electron redox system. 1 Recently, we reported reversible one-electron redox responses by the use of 4,7-disubstituted benzo-trichalcogenoles containing sulfur and/or selenium atoms and found by EPR spectroscopy that their radical cation salts obtained on treatment with one-electron oxidant had unusual 7π frameworks. 2 However, to date, ...
