 note = {In order to develop new redox systems which undergo reversible structural changes by electron transfer, bis(1,3-benzodithiolium)-type dications (5 21) containing a biaryl unit have been synthesized by hydride abstraction of the corresponding bis(1,3-benzodithiol-2-yl)biaryis (8). Reduction of 5 2, with zinc gave the corresponding intramolecular cyclization products (6), which reverted to 5(2+) by oxidation. Cyclic voltammetry also showed the efficient interconversion between both states. X-Ray analyses revealed that the twist angle of the biaryl unit decreases largely by reductive intramolecular cyclization., Article, HETEROCYCLES. 69(1): 365 (2006)},
