โฆ Synopsis
The reduction at the dme of aand #?-substituted anthraquinones, phenazines and phenazinc N,N' dioxides, and also of pnitrodiphenyls and pnitrostilbenes, to anion-radicals has been studied in aprotic media. The half-wave potentials of the l-electron process are shown to correlate in a linear manner with the energy of the lowest vacant orbital (in Hiickel's approximation) of the reduced substance.
