aprotic media yields superoxide anions O2.−. These highly reactiveradicalanions easily attack sensitive arenes. It is, therefore, not possible to generate the radicalanions of anthracene-9-carboxylic esters (1) by direct in situ electroreduction. Because derivatives substituted in the 10-position are stable against these radicals, indirect generation of the radicalanion 1.− was realized in order to
