Abstract: | 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.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 47–40, January, 1991. |
