2,5-Bis(3,5-di-t-butyl-4-oxo-cyclohexa-2,5-dien-1-ylidene)-2,5-dihydro-1,4-dithiapentalene: a new class of amphoteric multistage redox systems consisting of both the Wurster and the Weitz types

Abstract

The dihydrodithiapentalene-extended diphenoquinone DTP-DQ (1) has been synthesized and characterized as a hitherto unknown amphoteric four-stage one-electron redox system involving both a two-stage one-electron redox reaction of the Weitz type and a two-stage one-electron redox reaction of the Wurster type.
