Oxidation-reduction characteristics of octahydrochalcogenoxanthenes and octahydroxanthylium cations
Unstable radical-cations, which fragment according to the (−e, −H+, −e) scheme, are formed during the electrochemical oxidation of chalcogenooctahydroxanthenes. Free radicals (identified by ESR) are formed during the electrochemical reduction of the chalcogenooctahydroxanthylium cations.
