Electrochemical synthesis and mechanestic study of quinone imines exploiting the dual character of N,N-dialkyl-p-phenylenediamines

Two one-pot electrochemical approaches for the synthesis of similar quinone imines via either the nucleophilic character of N,N-dialkyl-pphenylenediamines or electrophilic reactivity of their oxidized forms through Michael-type addition reactions are reported.
